Question: Calculate the following:

a)      24+  -4

b)      10 -(-3)

c)      13 ×-6

d)      -45 ÷-9

a) Adding a minus number is equivalent to a subtraction. So, we get

24 + -4 = 24-4 = 20

b) Subtracting a minus number is equivalent to an addition. So, we get

10 - (-3) = 10+3=13

c) When you multiply a positive by a negative, the result should be negative:

13 \times 6 = 78,\,\,\text{ therefore }\,\,13 \times -6 = -78

d) When you divide two negative numbers, the result should be positive:

45 \div 9 = 5,\,\,\text{ therefore }\,\, -45 \div -9 = 5
