1. 6th grade Notes

2. Order of Operations
Evaluate expressions by using the order of operations…
Parenthesis- from left to right
Exponents-(you won’t see these in 6th grade order of operations)
Multiplication and Division- From left to right
Addition and Subtraction-From left to right

3. Order of Operations continued
7 − 18 ÷ = Work division first
7 − = Then subtraction because it come first from left to right.
1 + 1= Lastly, addition. 2

4. Order of Operations Continued
14 + (10 − 7 ) ∙ 3 = First work parenthesis.
∙ 3 = Next work multiplication (the dot represents multiplication.
= Last addition. 23

5. 3² The 3 is the Base and the 2 is the exponent.
Exponents
Exponent- tells you how many times a number is multiplied by itself.
Base- the number that you are multiplying by itself.
3² The 3 is the Base and the 2 is the exponent.
Means: 3 x 3 = 9

6. Exponents Continued 4³ = 4 x 4 x 4 = 16 x 4 = 64
Remember that you have to multiply the base (the big number) by itself the number of the exponent.
So if you have 6 to the power of 5 it means to multiply 6 x 6 x 6 x 6 x 6… It does not equal 30!!!!!!!!!!!!!!!!!!!!
