Destiny Glass 1.03 Applying Order of Operation July 14, 2019 1. Simplify the expression 7 2(2 + 5) 8 First, add the numbers in the parenthesis, then multiply 2*7 which equals 14. Subtract 7 – 14, which equals -7. Subtract -7 – 8 = -15 . 7 2(2 + 5) 8 (solve within the parenthesis first, there are no exponents) 7 – 2(7) – 8 (multiplication of the parenthesis) 7 – 14 – 8 (subtraction) -7 – 8 = -15 (subtraction) 2. Simplify the expression 15 + 3 2(2 1) First, subtract the number in the parenthesis then multiply 2*1 which equals 2. Next add 15 + 3, then subtract 18 -2 = 16 . 15 + 3 2(2 1) (solve within the parenthesis, no exponents) 15 + 3 – 2(1) (multiplication of the parenthesis) 15 + 3 – 2 (addition) 18 – 2 = 16 (subtraction) 3. Simply the expression 3[9 – (2 + 3 ) ] ! First, add the number inside the parenthesis. Subtract 9- 5, which equals 4. Bring down the 3 and evaluate the exponent. The finals step is to multiply 3*16. 3[9 – (2 + 3 )
