Hidden Picture

Solve four sums, then colour every square with your answers. A picture appears: a house, a rocket, a snowman… Sums to 10 or to 20.

How to play

Type the answer next to each sum; a box turns green when it's right. When all four are right, tap every square in the grid that holds one of your answers. Wrong squares flash red. Colour them all to see the picture, then try a new one.
