Example Question #1 :Multiply And Divide Rational Numbers Using Properties Of Operations: Ccss.Math.Content.7.Ns.A.2c
Let's work from left to right since it's only multiplication and division. Since there is only one negative number, the product ofis negative which is. Now we have. Two negative numbers in a division problem makes the answer positive.
Example Question #2 :Multiply And Divide Rational Numbers Using Properties Of Operations: Ccss.Math.Content.7.Ns.A.2c
Solve:
When solving this problem remember our orders of operation, or PEMDAS.
PEMDAS stands for parentheses, exponents, multiplication/division, and addition/subtraction. When you have a problem with several different operations, you need to solve the problem in this order and you work from left to right for multiplication/division and addition/subtraction.
Simplify the quantities inside the parentheses. Then multiply and distribute the coefficient in front.
