  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 ÷ 3 + 1 = Work division first • 7 − 6 + 1 = 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. • 14 + 3 ∙ 3 = Next work multiplication (the dot represents multiplication. • 14 + 9 = Last addition. • 23

  5. 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!!!!!!!!!!!!!!!!!!!!
