**Order of Operations with Exponents**

** **The rule to evaluate the value of a mathematical expression that includes exponents [e.g. ( -6 ÷ 3) x 8 ], is **PEMDAS . ** PEMDAS Stands for P: Parentheses, E: Exponents , M:Multiplication , D: Division, A: Addition and S: Subtraction.

**What do you do first in order of operations ?**

The following steps must be followed to solve a mathematical expression that includes an exponents:

Step 1: Operations inside the parentheses should be solved first .

Step 2: After performing operations inside of parenthesis , solve the exponents .

Step 3: After the parentheses and the exponents, perform multiplication or division from left to right depending on which operation comes first.

Step 4: Finally, after multiplication and division, perform addition and subtraction from left to right depending on which operation comes first.

**Order of Operations with Exponents(Solved examples) **

**(i)** (9+43-4) -8-

Sol. (9+43-4) -8-

= 48-8-9 (solving exponent)

=31 (performing subtraction)

**(ii) **33+10-

Sol. 33+10-

=33+10-2 (performing division)

=33+10-62 (performing multiplication)

= 43-62 (performing addition)

= -19 (performing subtraction)

**(iii) 70÷7-**

Sol. 70÷7-= 70÷7-27 (performing exponent)

=10-27 (performing division)

=-17 (solving subtraction)

**(iv) **

**÷ 4**

Sol. ÷ 4 = (1 x 4+27) -32 ÷ 4

=( 4+27) -32 ÷ 4

=31-32 ÷ 4

= 31- 8

= 23

**(v)** 25-8 x 2 +

Sol. 25-8 x 2 + =25-8 x 2 +9

= 25-16 +9

=9+9

=18

**(vi) **

**÷ 4**

Sol. ÷ 4** =**

**÷ 4**

= 81 +3 x 16÷ 4

=81+48 ÷ 4

=81+12

=93

**(vii) 36÷ **

Sol. 36÷

**=**36÷[20-8] (solving the operations inside the parentheses)

=36 ÷12

=36÷12+16-6 (solving exponent)

=3+16-6 (performing division)

=19-6 (solving addition)

=13

**(viii)**

Sol.

=

=50-2+16

= 48+16

= 64

**(ix) ( ÷ 15) **

Sol. **(÷ 15**)

**=**(3 x 25 ÷ 15) -(5-4)

=(75 ÷15)-(5-4)

= 5-4

=1

**(x) ÷**

Sol. ** ÷**

**= 2 x 6 ÷ 6 – +3 x 4**

= 2 x 6 ÷ 6 – 8 +3 x 4

= 12 ÷ 6 – 8 +3 x 4

=2 – 8 +3 x 4

=2-8+12

=-6+12

=6
