• 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 = 2,640 • 1

• 5,280 X = 2,640• 5,280 5,280

• X = 0.5 mi same as ½

You all know how to add, subtract,

multiply, and divide.

12/3/2014 Order of Operations

Parentheses: Simplify the expressions inside grouping symbols like parenthesesExponents 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…

Now it is your turn to try!

Next

What should I solve first in 5 x 3 – (2 + 2) ?

5 x 3

2 + 2

3 - 2

5 + 2

That is correct!You remembered that you solve inside the parentheses ( ) first!

What should I solve first in 6 + 4 x 3?

4 x 3

6 + 3

6 + 4

10 x 3

That is correct!

You remembered to multiply and divide before you add and

subtract!
