I Used My Fingers Under the Desk in College (And Why That Matters for Your Child)

: An honor student and math tutor's confession about counting on fingers — and why the teaching method matters more than you think.

I have a confession to make.

I was an honor student. I tutored math in college. I got good grades. People thought I was “smart.”

And I counted on my fingers under the desk.

Not in elementary school. Not just in middle school.
In. College.

I’d gotten really good at hiding it. I’d wait until I could subtly count on my fingers below desk level, out of sight. Sometimes I’d excuse myself to the bathroom so I could use my fingers privately. I developed this elaborate system of tapping my pencil in patterns that corresponded to counting.

It’s kind of hilarious now, looking back.

But at the time? I was SO ashamed.

How could I be “good at math” when I couldn’t even add simple numbers without counting on my fingers? What if someone found out? What if they realized I was a fraud?

You're Not Alone

After I started being open about this, you know what happened?

People started confessing to me.

“I use my fingers too! I just got good at hiding it.”

“I use my TOES. I have to take my shoes off sometimes.”

“I’m 45 years old and I still can’t add without fingers. Is that normal?”

One friend told me her sister uses both fingers AND toes.

She’ll literally take her shoes off during a meeting if she has to calculate something.

We laughed about it. But here’s the thing — it’s not actually funny.

It’s not because these people are “bad at math” or “not smart enough.”

It’s because they were taught using methods that create dependency.

The Crutch That Never Goes Away

When you teach a child to add using fingers, here’s what happens:

Step 1: They use fingers to figure out 5 + 3. Makes sense! It’s concrete. It’s visual.

Step 2: You assume that as they practice, they’ll naturally move past the fingers to mental math.

Step 3: They don’t. The finger-counting becomes more discreet, but it never goes away.

Step 4: Five years later, they’re still counting on fingers — they’ve just gotten better at hiding it.

I was that kid. And then I became that adult. And I’m FAR from alone.

The "Deer in the Headlights" Moment

Have you ever had someone ask you a relatively simple “How many is that?” question, and because you’re without paper and time and PRIVACY, for heaven’s sake, you get that “deer in the headlights” feeling?

Your mind goes blank. You panic. You can feel everyone watching you.

You KNOW you should be able to figure this out. It’s not that hard! But your brain won’t cooperate without your fingers, and you can’t use your fingers because people are WATCHING.

So you guess. Or you stall. Or you say “I’m not good at math” and laugh it off.

And inside, you die a little.

Because you KNOW you’re smart. You KNOW this shouldn’t be this hard.

But the method you were taught has made you dependent on external crutches.

It's the Method, Not the Kid

Here’s what I wish I’d known as a child:

I wasn’t bad at math. I was taught badly.

Traditional math teaching gives kids EXTERNAL crutches:
— Fingers to count
— Beads to manipulate
— Dots to draw
— Songs to sing

And these crutches FEEL helpful at first! They make early math accessible. Kids can see it, touch it, count it.

But here’s the problem: those crutches become permanent.
The child’s brain learns to DEPEND on external tools instead of developing INTERNAL mental processes.

It’s like teaching someone to walk on crutches and then being surprised they can’t walk without them.

What About Your Child?

Right now, you might be thinking about your own child.

Maybe they’re 7 and they count on their fingers for everything.

Maybe they’re 10 and you’ve noticed they still can’t add without finger-counting — and you’re starting to worry.

Maybe they’re 13 and they’re SO FRUSTRATED because math takes them three times longer than their friends, and you don’t know how to help.

Let me tell you what I wish someone had told my parents:
It’s not too late. But you need to change the METHOD, not just practice more.

Practicing the wrong method more intensely just makes kids better at using crutches.

What you need is a method that builds INTERNAL mental processes from the very beginning.

Why MathHacked Is Different

When I developed this system, finger-counting was one of the main things I was trying to prevent.

Because I’d LIVED the consequences. I’d FELT the shame. I’d experienced the limitation it created.

So our method:

— Never uses fingers as a counting tool
— Builds mental pattern recognition instead
— Strengthens the BRAIN as the primary tool
— Creates automatic recall, not figuring

The result? Kids don’t develop the finger-counting dependency in the first place. Or, if they already have it, they learn to work PAST it — to let their brain take over.

"But My Child Is Already Using Fingers…"

This is the question I get all the time: “My child is 8/9/10 and has been counting on fingers for years. Is it too late?”
Here’s my honest answer: No. But you need to make a deliberate switch.

If they’re using fingers for addition and subtraction, I’d actually STOP that work temporarily and start fresh with multiplication — taught the MathHacked way.

I know that sounds radical. But here’s why it works:

When they learn multiplication without external crutches — when their BRAIN becomes the tool — they develop new neural pathways. New ways of working with numbers.

Then, when you come back to addition and subtraction, they approach it differently. They’ve been trained in mental figuring. They’re less likely to reach for their fingers.

The habit isn’t instantly broken, but you’ve given them an alternative pathway. A way to work that doesn’t require crutches.

The College Bathroom Moment

You know what finally broke me of finger-counting?

I was in college, taking a test. I needed to add something simple — probably 7 + 8 or something equally basic.

I couldn’t use my fingers (people were watching).

I sat there, panicking, for what felt like an eternity.

And then — I don’t know how to explain this — something clicked. My brain just…found it. Without fingers. Without anything external.

It was like a door opened that I didn’t know existed.

And I remember thinking: “Why didn’t anyone teach me this FIRST? Why did I have to figure this out on my own in a college bathroom during a test?”

What I Want for Your Child

I don’t want your child to be like me.

I don’t want them to get to college still counting on fingers.

I don’t want them to develop elaborate hiding techniques.

I don’t want them to have that “deer in the headlights” panic when someone asks them a simple math question.

I don’t want them to believe they’re “bad at math” when they’re actually just using a bad method.

What I WANT is for them to discover — early — that their BRAIN is capable of figuring. That they don’t need external crutches. That they’re actually quite brilliant at this.

And that’s exactly what MathHacked does.

From day one, we position the brain as the hero. The tool. The source of answers.

Not fingers. Not beads. Not songs.

Their brain.

And when kids discover that? When they realize they can actually FIGURE things in their head?

It changes everything.

Is your child still counting on fingers? It’s not their fault — and it’s not too late.

MathHacked was designed specifically to break the finger-counting habit and replace it with something far more powerful — a brain that figures automatically, confidently, and without crutches. Try it risk-free for 30 days and see the difference for yourself.
