PEMDAS is the order of operations....it is the order u solve equations.
P = parenthesis....u solve what is in parenthesis first
E = exponents...u solve the exponents next
M = multiply , D = divide....starting from left and going right, u do all the multiplying and dividing
A = addition, S = subtraction...starting from left and going right, u do all the addition and subtraction
With adding and subtracting fractions, you must find a common denominator. In multiplication, you just multiply numerator by numerator; denominator by denominator. In division, you multiply the fraction by the reciprocal of the 2nd. In multiplication and division, finding a common denominator is not needed.
