enter numbers to evaluate ‐13−(‐23).

‐13−(‐23)= ‐13 +

=

- 13 - 23 = - 13 + (-23)

= -36

- 13 - (- 23) = - 13 + 23

= 10

Step-by-step explanation:

In any order of operation (i.e. addition, subtraction, multiplication, devision) the following rules apply for two values for instance a and b where a > b :

→ If +a and +b then the final sign will be + (positive)

→ If +a and -b then the final sign will be + (positive) since a>b

→ If -a and +b then the final sign will be - (negative) since a>b

→ If -a and -b then the final sign will be - (negative)

In the given question we have two cases.

Case 1:

- 13 - 23 = - 13 + (-23)     → since it is given that we add a negative value of -23, therefore it keeps its sign (so this would be a negative addition i.e. adding two negative values)

Thus we have:

- 13 - 23 = - 13 + (-23)

= -36

Case 2:

- 13 - (- 23) = - 13 + 23     → since we stated earlier that - and - gives positive sign (i.e. we subtract two negative values)

Thus we have:

- 13 - (- 23) = - 13 + 23

= 10

So we can see that:

Adding two Negative values gives a Negative value (Case 1)

Subtracting two Negative values gives a Positive value (Case 2)

answer: 12

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
