I have chosen 4 and 1 as those are the ages of my sons. (I might reveal my number if more people have a go at this challenge!)
Here are some of the ways I can make 4…
2 + 2, 10 – 6, 2 x 2, 2², 0.5 x 8, 1/4 x 16, 16 ÷ 4 and 400 ÷ 100. It can be divided into whole numbers by 1, 2 and 4 and so it is not a prime number (it is a composite number).
Here are some of the ways I can make 1…
100 – 99, 0 + 1, -2 + 3, 1 x 1, 8 ÷ 8, 0.75 + 0.25, 1/3 + 2/3.
