My son was given a challenge division sheet to be done during a school lesson.
He said he struggled for ages with question 14:
Put brackets into this expression to make it correct.
$10^2 ÷ 10 ÷ 10 ÷ 10 ÷ 10 = 10$
I tried to help but I could not see any way to make this work - it seems you will always end up with an even power of 10 on the left hand side. Can anyone tell us what we are missing?
