  • Today we are talking about how to solve a problem with multipleoperations.
  • (4 + 6)^2/(2 ∗ 5) − 10 + 3 ∗ 5 = x
  • Parenthesis, Exponents, Multiplication, Division, Addition, SubtractionWe will be using PEMDAS:
  • Jason can you tell me what the first step is?
  • 10^2/(10) − 10 + 3 ∗ 5 = x
  • We first need to do Parenthesis
  • Awesome!Thea can you tell us what we would need to do then?
  • The Parenthesis would be the (4+6) and (2*5) because you have to treat the division symbol like a parenthesis
  • 100/(10)− 10 + 3 ∗ 5 = x
  • Great job Thea.Murphey what is the next step?
  • We next need to  do the exponents of (10)^2
  • Jason what is the next step?
  • We now need to do the Multiplication which is 3+5
  • 100/(10) − 10 + 15 = x
  • 10 − 10 + 15 = x
  • And Murphey what does the D stand for in PEMDAS
  • The D stands for Division. So that means we have to do 100/(10)
  • 15 = x
  • Thea what are the last two steps we have to do?
  • We now do addition and subtraction which is the10-10+15. So x=15 since10-10 = 0 and we are only left with +15.
