It is 28. If you just wanted the quick answer because you're staring at a math worksheet or trying to split a very specific dinner bill, there you go. 4 times 7 is 28.
But why does this specific equation feel like a mental speed bump for so many people? Seriously. Ask a room of adults to multiply 5 times 10, and the answer is instant. Ask them what 4 times 7 is, and you’ll see a flicker of hesitation in their eyes. It’s that half-second lag where the brain scrambles to find the file. Honestly, it’s one of those "middle-ground" multiplication facts that isn't quite as easy as the 2s or 5s, but isn't as notoriously "scary" as the 7 times 8 hurdle.
The Psychology of 28
Math isn't just about numbers; it’s about how our brains store data. Cognitive scientists like Jo Boaler from Stanford have spent years looking at how we memorize math facts. She’s often argued that rote memorization without "number sense" is why we get stuck. When you think about 4 times 7, your brain is trying to access a retrieval pathway. If that path is dusty, you stumble.
Why is 28 "dusty"?
It’s because it doesn't have a distinct "rhythm" in our base-10 counting system. Multiples of five end in 5 or 0. Multiples of two are always even and feel "round." But 28? It’s just... there. It’s sitting in that awkward territory of the 7-times table, which is statistically the hardest table for most humans to memorize.
Visualizing 4 Times 7
If you’re struggling to remember it, stop trying to memorize the sound of the words "four times seven is twenty-eight." Start looking at what the number actually looks like in the real world.
Imagine a standard month. Most months are roughly four weeks long. A week has seven days. 4 weeks x 7 days = 28 days. That is exactly why February (usually) has 28 days. When you realize that the entire month of February is literally just 4 times 7, the number sticks. It’s no longer an abstract concept; it’s a calendar.
Breaking it Down for the Rest of Us
If the direct route to 28 is blocked, use a detour. This is called "decomposition."
- The Double-Double Rule: This is the easiest way to handle any multiple of four. You just double the other number, and then double it again. Double 7 is 14. Double 14 is 28. It’s a two-step process that feels way faster than trying to count by sevens.
- The Five-Minus-One Strategy: If you know that 5 times 7 is 35 (and most people do, because 5s are easy), just subtract one group of 7. 35 minus 7 is 28.
Most people use these "hidden" tricks without even realizing it. It’s how "math people" seem to calculate so fast. They aren't necessarily better at memorizing; they're just better at finding the shortest path between two points.
Why Does This Matter in 2026?
We have calculators on our wrists. We have AI that can solve complex calculus in a heartbeat. So, who cares about 4 times 7?

It’s about "computational fluency." Research suggests that when we offload even the simplest arithmetic to devices, we lose our ability to estimate. Estimation is a survival skill. If you're at a grocery store and see four items priced at $7 each, and your brain can't instantly ping "28," you're more likely to get overcharged without noticing.
It also shows up in weird places like gaming. If you’re playing a tabletop RPG and you deal 4d7 damage (unusual dice, but they exist!), knowing that 28 is your ceiling matters for your strategy.
Common Misconceptions About the 7s
People often think they are "bad at math" because they can't remember the 7-times table. That’s total nonsense. The 7s are objectively harder because 7 is a prime number and doesn't follow the easy visual patterns of 2, 4, 6, or 8.
Some people mix up 28 with 24 (which is 4 times 6) or 32 (4 times 8). This usually happens because our brains are better at remembering "rhymes" or "sequences" than pure logic.
The Best Way to Teach It
If you’re helping a kid (or yourself) learn this, skip the flashcards for a minute. Try an array.
Draw four rows of seven dots.
Or seven rows of four dots.
Seeing the rectangle that these numbers form creates a "spatial" memory. This is what educators call "Area Model" multiplication. It’s the foundation for high school algebra. When you see 4 times 7 as a shape, you stop guessing and start knowing.
Practical Steps to Master Multiplication
Stop stressing about speed. Stress creates cortisol, and cortisol literally blocks the part of your brain responsible for memory retrieval. It’s a vicious cycle.
- Use the February Shortcut: Always associate 4x7 with a non-leap-year February.
- The "Double-Double": Practice doubling numbers in your head while driving or walking. If you can double 7, you can find 4x7.
- Look for 28s: Start noticing where 28 pops up in life. A deck of cards has 28 cards if you remove the face cards and aces? No, that's not right. But a standard set of double-six dominoes has exactly 28 tiles.
Knowing 4 times 7 is a small thing. But small things build the confidence to handle big things.
The next time someone asks you what 4 times 7 is, don't panic. Think of February. Think of double-14. The answer is 28, and you've got it.
To keep this fresh, try to calculate your next few small purchases manually before looking at the receipt. Start with multiples of 4 and 7 specifically to build that mental muscle. You'll find that within a week, the hesitation disappears entirely.
