In a SATs Paper A you might be asked to solve a simple one-step
question that requires you to subtract one value from another value, for
example:
Barry has a box of 65 chocolates.
He gives 19 to his friends.
How many are left in the box?
This can be solved two ways:
a)Count on from the small number (in this case 19) until the big number (in
this case 65):
19 + 46 = 65
46

A similar example would be:
A shop sells three colours of t-shirts;
Red t-shirts at £2.69 each
Blue t-shirts at £7.50 each
White t-shirts at £4.99 each
What is the difference in price between the cheapest t-shirt and the most
expensive t-shirt?
This can be solved in one of two ways:
a)Count on from the lowest price (in this case £2.69) until the biggest price
(in this case £7.50):
£2.69 + £4.81 = £7.50
b)Subtract the lowest price from the biggest price:
£7.50 – £2.69 = £4.81
Either way the difference is £4.81
