Here a few few extra’s to get your maths minds working:
Start with the number 5, +7, halve it, x 12, – 9, divide by 7, + 16, x 2, -48, x 11= ?
Start with the number 16, a quarter of it, +81, divide by 5, x 6, – 44, halve it, + 47, 3/4 of it, + 19 = ?
Start with the number 401, – 86, 80% of it, x 3, halve it, -231, 4/7 of it, x 4, + 25, square root of this = ?
You can’t count the hairs on your head. What are 3 other things that you can’t count.
