6th grade Notes
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
Order of Operations continued 7 − 18 ÷ 3 + 1 = Work division first 7 − 6 + 1 = Then subtraction because it come first from left to right. 1 + 1= Lastly, addition. 2
Order of Operations Continued 14 + (10 − 7 ) ∙ 3 = First work parenthesis. 14 + 3 ∙ 3 = Next work multiplication (the dot represents multiplication. 14 + 9 = Last addition. 23
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
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!!!!!!!!!!!!!!!!!!!!
