Question:  Using the numbers 10, 1, 5, 4, 25 and 2, I need to make 983. You can use the numbers only once each but you can use these: add, subtract, divide and multiply as many times as you like.

Answer:  Here is a suggested answer:

Multiply 25 by 4 to get 100

Subtract 1 from 100 to get 99

Multiply 99 by 10 to get 990

Subtract 5 to get 985

Subtract 2 to get 983 (Your answer)

(25 x 4) = (100 - 1) = (99 x 10) = (990 - 5) = (985 - 2) = 983

It's worth practising a lot of these on your own just to get the feel of the numbers. Brackets are very useful.
