Negative numbers:

Subtracting negative numbers:

10 – 4 = 6

10 – 3 = 7

10 – 2 = 8

10 – 1 = 9

10 – 0 = 10

If the pattern continued, the number subtracted becomes negative and the answer continues to increase by 1.

10 – (–1) = 11

10 – (–2) = 12

10 – (–3) = 13

It can be seen that the result of subtracting a negative number is the same as adding it as a positive number: 10 – (–3) = 10 + 3 = 13

★★★Therefore subtracting negative number makes the answer bigger.★★★

Multiplication and division by negative numbers

3 × 4 = 12

2 × 4 = 8

1 × 4 = 4

0 × 4 = 0

If the multiplication continued, the answers follow the same pattern.

(–1) × 4 = –4

(–2) × 4 = –8

(–3) × 4 = –12

You can see that if a positive number is multiplied by a negative number the answer is negative too.

As –3 × 4 = –12 it follows –12 ÷ 4 = –3

★★★So multiplication and division are the same just multiply or divide the number as it positive and add the negative sign (–).★★★
