Order of Operations, GEMDAS

Use the Order of Operations to simplify numeric expressions. Find the value of the expression.

Multiple Choice

$$What\ is\ the\ first\ step?\ \ \ 3^2-\left(1+2\right)+5\times2\div2$$  

• First Do  $$3^2$$  

• Do (1+2) first

• Do multiply first

• divide first

Multiple Choice

$$=\ 3^2-3+5\times2\div2\ \ \ \ \ \ \ \ Now\ what?$$  

• $$3^2\ \$$  comes next which is 6

• $$3^2$$   comes next which is 3*3 or 9

• divide next

• subtract next

Multiple Choice

$$=\ 9-3+5\times2\div2\ \ \ \ Now\ what?$$  

• Now we can subtract 9 - 3

• Now we can add 3+5

• Now we divide 2 by 2 (since on right)

• Now we multiply 5 by 2 (since on left)

Multiple Choice

$$=\ 9-3+10\div2\ \ \ \ Now\ what?$$  

• Now we can subtract because it's on the left

• Next we need to add because adding is more powerful and important

• Now we divide 10 by 2

• We can do anything we want and still get the right answer.

Multiple Choice

$$=\ 9-3+5\ \ \ \ \ Now\ what?$$  

• Now we subtract 9 and 3 since it's on the left

• Now we add 3 and 5 because that is easiest

• We can do anything we want and still get the right answer.

• I'm not sure

Multiple Choice

$$=\ 9-3+5\ \ \ \ \ What\ does\ this\ simplify\ to?$$  

• The final answer is 1

• The final answer is 11

• The final answer is not shown here

• I'm not sure

Multiple Choice

$$Find\ the\ value\ \left(simplify\right):\ \ 2\times\left(1+2\right)^2-5+3$$  

• The value is 13

• The value is 10

• The value is 16

• The value is not listed here.
