From your previous lessons, you have learned the fundamental operations involving real numbers

and the correct order of operations, commonly known as PEMDAS or GEMDAS (Parentheses/

Grouping, Exponent, Multiplication, Division, Addition, Subtraction) rule.

To further check your readiness for this lesson, simplify the following:​

To further check your readiness for this lesson, simplify the following:

Same sign = add (copy the common sign as an answer)

Opposite sign = subtract (copy the sign of the bigger number)

A.

  • 12 + 8 = 20
  • 12 + (-8) = 4
  • -12 + 8 = -4
  • -12 + (-8) = -20

B.

  • 12 - 8 = 4
  • 12 - (-8) = 20
  • -12 - 8 = -20
  • -12 - (-8) = -4

C.

  • 8 + 8² ÷ 8 = 8 + (64 ÷ 8) = 8 + 8 = 16
  • 2 + 2 × 2 - 2² = 2 + 2 × 2 - 4 = 2 + 4 - 4 = 2 + 0 = 2
  • 5 - 5(5 + 5) + 5² = 5 - 5(10) + 25 = 5 - 50 + 25 = -45 + 25 = -20

A.

12+8=20

12+(-8)=4

-12+8= -4

-12+(-8)= -20

B.

12-8=4

12-(-8)=20

-12-8= -20

-12-(-8)= -4

C.

8+8²÷8=16

2+2×2-2²=2

5-5(5+5)+5²= -20

=========================

TIPS:

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.
