BIDMASter app for iPhone and iPad

Drag numbers and symbols from the keyboard so they equal the target number.

Use the rules for the correct order of operations (rules in App)

For example:

Target 28 First guess might be ( 3 + 4 ) x 4

Tap ‘=‘ and see how close you are to the hidden solution.

Each number or symbol is coloured as follows:

GOLD in the right place

BLUE in the wrong place and needs moving

GREY not needed at all

You can now rearrange and remove numbers or symbols to come up with a second attempt, and so on.

Flick a character up or down to remove it.

You get six attempts in total.

When you’ve mastered level 1, try level 2.

This game is ideal if you like Wordle and fancy a go at numbers instead of letters.

And it’s a stimulating and fun way to start a maths lesson.
