Math Class

1. Check which operation each problem uses: +, −, × or ÷.
2. Work out the answer.
3. Give it with the mouse or by touch.
4. Keep going: the calculations get harder as the levels go up.

Math Class is a straightforward way to practice all four operations in one place. Problems cover addition, subtraction, multiplication and division, and the difficulty changes with the level you're on, so beginners start with manageable sums while stronger players get tougher calculations. Because the operations are mixed rather than drilled one at a time, it trains you to read each problem carefully before answering — a habit that helps with real schoolwork. It plays with a mouse or touch in any browser.

With all four operations mixed together, the first step is always to read the sign. A reliable routine is: read the sign, estimate, calculate, then check with the opposite operation. If 84 ÷ 7 = 12, then 12 × 7 should give 84; if 53 − 19 = 34, then 34 + 19 should give 53. It also helps to know which operations can be swapped: 3 + 8 and 8 + 3 match, as do 4 × 7 and 7 × 4, but 9 − 4 is not the same as 4 − 9, and 12 ÷ 3 is not 3 ÷ 12.
