Each skill explained clearly — with everyday examples
The belt colors correspond to the Dojo Mode in the Math Fighter app. Both modes (KIDS and STUDENT) have all 8 belts with different difficulty levels. Topics are aligned with common school curricula.
For kids aged 6 to 12. All 8 belts are playable! Tasks are age-appropriate — with pictures, stories, and simple language.
| Belt | Grade | Topics | Difficulty |
|---|---|---|---|
| White Belt | 1–2 | Addition, Subtraction, Doubles, Halves (1–20) — with apples, candies and fingers | 🟢 Easy |
| Yellow Belt | 2–3 | Addition & Subtraction up to 100 — step by step with carrying | 🟢 Easy |
| Orange Belt | 3–5 | Times tables, Division, simple percent (50%, 25%) | 🟠 Medium |
| Green Belt | 4–6 | Order of Operations, Parentheses — kid-friendly examples | 🟠 Medium |
| Blue Belt | 5–6 | Fractions, Decimals, Conversion | 🟠 Challenging |
| Brown Belt | 5–7 | Geometry (Area, Perimeter), Powers | 🔴 Hard |
| Black Belt | 7–8 | Simple equations (find x), Summation | 🔴 Very hard |
| 2nd DAN | 8–9+ | Simple functions f(x) — plug in values | 🔴 Very hard |
For students and adults aged 13 to 99. More direct explanations, higher numbers, and more complex tasks. All belts in Math Fighter are achievable.

What is it? Adding two or more numbers together.
💡 Tip: Use your fingers to count — everyone does it at the beginning!
What is it? Taking one number away from another.
💡 Tip: Imagine giving something away — what's left?
What is it? Multiplying a number by 2 (doubling) or dividing by 2 (halving).
💡 Tip: Doubling means adding the number to itself! 6 + 6 = 12.
What is it? Addition and subtraction with two-digit numbers — with carrying over tens.
💡 Tip: Break down hard problems: 83 - 27 → first 83 - 7 = 76, then 76 - 20 = 56.
What is it? Quick addition of equal groups.
💡 Tip: Multiplication is like fast addition — 3 × 2 is the same as 2 + 2 + 2!
What is it? Sharing fairly into equal groups.
💡 Tip: Division is the opposite of multiplication — fair sharing!
What is it? Calculating parts of 100 — the most common: 10%, 25%, 50%.
💡 Tip: 50% = half, 25% = quarter, 10% = tenth. Remember these three!
What is it? The rule that multiplication and division are always calculated BEFORE addition and subtraction.
💡 Tip: Remember: multiply and divide first, then add and subtract!
What is it? Parentheses change the order — what's inside parentheses is calculated first.
💡 Tip: Parentheses are the boss — they are ALWAYS calculated first!
What is it? Parts of a whole — a pizza cut into 4 slices, 1 slice = 1/4.
💡 Tip: Adding fractions: first find the same denominator, then add the numerators!
What is it? Fractions written as decimal numbers. 1/2 = 0.5 and 3/4 = 0.75.
💡 Tip: Remember: 1/2 = 0.5 | 1/4 = 0.25 | 3/4 = 0.75 | 1/5 = 0.2
What is it? Area = how much space a shape takes up. Perimeter = how long the edge is.
💡 Tip: Area = length × width. Perimeter = add all sides together!
What is it? Multiplying a number by itself. 3² = 3 × 3. 2³ = 2 × 2 × 2.
💡 Tip: The small number on top (exponent) tells you how many times to multiply!
What is it? Finding unknown numbers (x) by solving equations.
💡 Tip: Goal: get x alone on one side! Do the same thing on both sides.
What is it? A shorthand for 'add all numbers from ... to ...'.
💡 Tip: Σ is just an abbreviation for many plus signs in a row!
What is it? A formula that takes a number (x) and calculates a result.
💡 Tip: Plug in the number for x and calculate step by step!
What is it? Telling the time on a clock with hands. The short hand shows the hour, the long hand shows the minutes.
💡 Tip: Long hand on 12 = o'clock, on 3 = quarter past, on 6 = half past, on 9 = quarter to.
What is it? Knowing what coins and notes are worth, adding them up, and working out the change.
💡 Tip: Start counting with the biggest coin — it is quicker and you make fewer mistakes.
What is it? Reading a thermometer and calculating with degrees Celsius (°C).
💡 Tip: Water freezes at 0°C and boils at 100°C — between those two marks you can estimate everything else.
What is it? A tutor inside the app that teaches in a conversation, instead of only marking answers right or wrong.
💡 Good to know: The tutor is a Pro feature — the first message is free with 20 trial credits, Pro includes 300 credits a month. For children, a parent has to agree before it can be used.
