12/3/14 Warm up ORDER OF OPERATIONS small to Large = divide 5,280 ft = 1 mile (mi) 2,640 ft = mi
small to Large = divide 5,280 ft = 1 mile (mi) 2,640 ft = mi X = 1 mi 2,640 ft = 5,280 ft 5,280 X = 2, ,280 X = 2,640 5,280 5,280 X = 0.5 mi same as ½

12/3/2014 Order of Operations Parentheses: Simplify the expressions inside grouping symbols like parentheses Exponents and Square Roots: Find the value of all powers and square roots Multiply and Divide in order from Left to Right Add and Subtract in order from Left to Right
But what happens when all of those operations are in the same math problem? Next
There is a phrase we use to help us remember the order of operations… Next
Purple Elephants May Destory A School! Next
Purple 1. Solve inside parentheses ( ) Next
For Example: 10 + (5 - 4) x x 3 Next
May Destory 2. Multiply or Divide from left to right. Next
For Example: 10 + (5 - 4) x x Next
A School ! 2. Add or Subtract from left to right. Next
For Example: 10 + (5 - 4) x x Next
Now it is your turn to try! Next
What should I solve first in 5 x 3 – (2 + 2) ? 5 x
That is correct! You remembered that you solve inside the parentheses ( ) first! Next
Good Try, but remember that Purple Elephants May Destory A School ! Try Again
What should I solve first in x 3? 4 x x 3
That is correct! You remembered to multiply and divide before you add and subtract! Next
Good Try, but remember that Purple Elephants May Destory A School! Try Again
Solve: (5 + 2) x
That is correct! You remembered the Order of Operations! Next
Good Try, but remember that Purple Elephants May Destory A School ! Try Again
Solve: (20 + 2)
That is correct! You remembered the Order of Operations! Next
Good Try, but remember that Purple Elephants May Destory A School ! Try Again
Solve: 48 ÷ (8 - 2)
That is correct! You remembered the Order of Operations! Next
Good Try, but remember that Purple Elephants May Destory A School ! Try Again
Solve: 18 – (6 x 1) x
That is correct! You remembered the Order of Operations! Next
Good Try, but remember that Purple Elephants May Destory A School ! Try Again
Good Job! You now know a lot about the Order of Operations!
EXIT A (5 - 4) x 3 B. 5 x 3 – (2 + 2) Exit: A (5 - 4) x 3 B. 5 x 3 – (2 + 2)
Exit: A (5 - 4) x x
Exit : B. 5 x 3 – (2 + 2) 15 – 4 1
