Question

Is it Possible for the expression 1+|a| to have a result that is less than 0?

Answer 1

No

Explanation:

Because the vertical lines mean the absolute value of a.

- a negative value of a like -2 in vertical lines has absolute value 2.

If a = 0 then absolute value = 0.

So 1+|a| will always be positive.

Answer 2

No

Explanation:

Since a is in absolute value symbols, you would be adding a positive number to 1, and therefore cannot have a number lower than 0.

For example, say a = -3. We would get 1 + |-3| = 4.
