1-3 Practice: Algebraic Expressions

1. seven less than the number "t" is t - 7
2. the sum of 11 and the product of 2 and a number "r" is 2r + 11
3. Arin has $520 and is earning $75 each week babysitting. Algebraic Expression is 520 +75w
4. You have 50 boxes of raisins and are eating 12 boxes each month. AE is 50 - 12m

Evaluate each expression using the given values of the variables:

5. -4v + 3(w + 2v) - 5w; v = -2 and w = 4

-4(-2) + 3 (4 + 2(-2)) - 5(4) = 8 + 3(0) - 20 = -12

Adding and Subtracting

When adding or subtracting one number from another, we only have to work with one sign, either a plus (+) sign or a minus (-) sign. So when we have more than one sign right next to each other, how do we decide which one to use?

Here is a chart to assist you:

Two Signs . . . . Become One Sign
+ + . . . . . . . . . . . . +
+ - . . . . . . . . . . . . . -
- + . . . . . . . . . . . . . -
- - . . . . . . . . . . . . . . +

Try these practice problems by combining pairs of signs and solving.

1. 4 + (+12) =
2. -3 - (+15) =
3. 7 - (-6) =
4. 1 + (-8) =
5. 7 + (-2) - (-9) =
6. 14 - (+3) + (-5)=
7. -17 + (+30) - (-10) =
