How to enter answers
- Type plain integers:
11,20. - Remember: ×/÷ before +/−, and pairs go left to right.
- A fraction bar groups the top — compute it before dividing.
2 Problem types
The generator mixes these types at random.
Add then multiply trap
The classic: 3 + 4 × 2 = 11.
3+4×2
Parentheses first
Grouping outranks everything.
(2+3)×4
Mixed × and +
Both multiplications first.
2×3+4×5
÷ and × left to right
Same rung: leftmost wins.
12÷3×2
Exponents in the mix
Powers before products.
2+3²×2
Fraction bar grouping
Top first, then divide.
(8+4)/3
Nested grouping
Inside out.
2×(3+(4−1))
