A simple calculator with big buttons, made for children checking their sums. For small numbers it can draw the sum as dots, rows or equal groups, so your child sees why the answer is right, not just what it is. It also follows the order of operations, so 2 + 3 × 4 gives 14.
Free, no sign-up
Try a small sum like 6 + 3, 9 − 4, 3 × 4 or 12 ÷ 3, then press =.
Yes, it is free and works without an account on phones, tablets and computers.
It is best used to check answers after working a sum out on paper, or to explore patterns. Learning number facts by heart still matters.
For small whole-number sums it draws dots for adding, crosses out dots for taking away, shows rows for times and equal groups for sharing.
