PEMDAS
- ) P: First do parenthesis:
- 2(3+4)= 2(7)=14
- 2) E: Then do exponents:
- 2(3+4)2= 2(7)2=2(49)= 98
- (2x5 ) / (x3 ) = 2x(5-3)
- 3) MD: Then Multiplication and Division:
- 1 +6/2+4*3 = 1+ 3+12= 16
- When several multiplications and divisions occur together, go from left to right.
-

- 4) AS: Last comes addition and subtraction .
- When several additions and subtractions occur together, go from left to right.
