Question

Consinder this set of expressions.3 -4. -2 + -3. -5 - 4part a: Simplfy each expression.A: 3 =B: -4 =C: -2 + -3 =D: -5 - -4=part b: graph each value on the number line. label the points.

Answer 1

The absolute value of a negative number is the positive of that same number. Therefore,

Part A

`\lvert3\rvert=3`
`-\lvert4\rvert=-4`
`\lvert-2\rvert+\lvert-3\rvert=2+3=5`
`\lvert-5\rvert-\lvert4\rvert=5-4=1`

part B
