Example Question #1 :Add And Subtract Rational Numbers: Ccss.Math.Content.7.Ns.A.1d
Evaluate:
Break up the parentheses. Double negatives result in a positive sign, and positive with a negative sign will result in a negative sign.
Next, simplify by adding and subtracting each component from left to right.
Example Question #1 :Add And Subtract Rational Numbers: Ccss.Math.Content.7.Ns.A.1d
Subtract:
Eliminate the double negatives first.
Double negatives will result in a positive sign.
Simplify the terms.
Example Question #3 :Add And Subtract Rational Numbers: Ccss.Math.Content.7.Ns.A.1d
Solve.
Example Question #281 :Grade 7
Solve:
Let's work from left to right since it's only subtraction and addition. Sinceis greater thanand it's positive our answer is positive, but we treat this like a subtraction problem because theis negative.. Now we have.is greater thanand it's negative so our answer is negative and we treat this like a subtraction problem., but since our answer should be negative our answer is.
Example Question #282 :Grade 7
Solve:
Solve by first combining signs and eliminate the parentheses.
A positive multiplied with a negative sign will give a negative sign.
Example Question #283 :Grade 7
Use the number line provided to help solve the following problem:
In order to solve this problem, we need to start aton the number line.
Next, we havewhich means we need to moveplaces to the right on the number line. When we have an addition signwe move to the right because that is towards the positive side of the number line. When we have a subtraction signwe move to the left because that is towards the negative side of the number line.
