Addition | Answer | Example |
Sum of two positive integers | is always a positive number | 4 + 5 = 9 |
Sum of a positive and negative integer | is either positive or a negative number | 3 + -4 = -1 8 + -2 = 8 - 2 = 6 |
Sum of a negative and positive | is either positive number or a negative number | -3 + 4 = 1 -6 + 2 = -4 |
Sum of a two negative integers | is always a negative number | -3 + -4 = -7 -6 + -2 = -6 - 2 = -8 |
Subtraction | Answer | Example |
Difference of two positive integers | is either positive or a negative number | 7 - 5 = 2 5 - 7 = -2 |
Difference of a positive and negative integer | is always positive number | 3 - -4 = 3 + 4 = 7 6 - -2 = 8 |
Difference of a negative and positive integer | is always negative number | -3 - +4 = -3 - 4 = -7 -8 - +2 = -8 - 2 = -10 |
Difference of a two negative integers | is either positive or a negative number | -3 - -4 = -3 + 4 = 1 -6 - -2 = -6 + 2 = -4 |
Multiplication | Answer | Example |
Product of two positive integers | is always a positive number | 4 x 5 = 20 |
Product of a positive and negative integer | is always a negative integers | 3 x -4 = -12 |
Product of a negative and positive integer | is always a negative number | -3 x 4 = -12 |
Product of a two negative integers | is always a positive number | -3 x -4 = 12 -6 x -2 = 12 |
Division | Answer | Example |
Quotient of two positive integers | is always a positive number | 12/3 = 4 |
Quotient of a positive and negative integer | is always a negative number | 12/-4 = -3 |
Quotient of a negative and positive integer | is always a negative number | -12/4 = -3 |
Quotient of a two negative integers | is always a positive number | -12/-4 = 3 |
