How to Get Better at Mental Math: A Beginner's Guide for Adults

Let's be honest, for many of us, "mental math" feels like something we left behind in school. These days, we lean on calculators, spreadsheets, or phone apps for even the simplest sums.

But here's the truth: sharpening your mental math isn't just about calculating the bill at a restaurant without pulling out your phone. It's about keeping your brain active, saving time in everyday situations, and feeling more confident with numbers.

The good news? You don't have to be a "math person" to improve. With the right approach, anyone can get better.

1. Start Small and Build Up

If it's been a while since you last practiced, don't begin with complicated problems. Start with the basics:

• Add and subtract small numbers in your head
• Recall multiplication tables (start with 2s, 5s, and 10s)
• Estimate sums before calculating the exact number

Once you feel more comfortable, you can move on to larger numbers and multi-step calculations. Think of it like learning to walk before you run.

2. Break Numbers Into Friendlier Pieces

Big numbers can seem intimidating, but they're easier when you break them apart.

For example: 47 × 6 = (40 × 6) + (7 × 6) = 240 + 42 = 282

By splitting numbers, you simplify the process and make it less overwhelming.

3. Use Simple Shortcuts

A few quick tricks can make a big difference:

• Multiply by 5: Multiply by 10, then divide by 2.
  Example: 18 × 5 → 180 ÷ 2 = 90
• Add 9: Add 10, then subtract 1.
• Square numbers ending in 5: Multiply the first digit(s) by the next higher number, then add 25.
  Example: 35² 3 × 4 = 12 → 1225

These methods cut down the effort and speed things up.

4. Practice Through Everyday Life

You don't have to set aside study time—practice as you go about your day:

• Calculate discounts while shopping
• Estimate your grocery bill before checkout
• Work out travel times without a clock or map
• Split bills with friends in your head

The more you do it, the more natural it becomes.

5. Play With Numbers

Math doesn't have to feel like homework. Games like Sudoku, math puzzles, and mental math apps can make learning fun.

The more you enjoy the process, the more likely you'll stick with it.

6. Stay Consistent

Like any skill, mental math improves with regular practice. Even 5–10 minutes a day can bring noticeable progress in just a few weeks.

Be patient—speed and accuracy will come with time.
