Puzzle of the Day

These puzzles are also printed in Eight days a week, a booklet published by the Association of Teachers of Mathematics.

Use three twos in three different ways so the second answer is twice the first answer and half the third answer. You can put add, take, times or divide between the twos. e.g. 2÷2+2=3

Answer: answers could be 0.5, 1 and 2 eg 2÷(2x2)=0.5, 2-(2÷2)=1 and (2+2)÷2=2 but also (2-2)x2=0, (2-2)÷2=0 and 2x(2-2)=0 would be allowed
