subtraction of integers

Front

What is the result of subtracting a negative integer from a negative integer?

Back

When you subtract a negative integer from a negative integer, it is equivalent to adding the absolute value of that negative integer. For example, -8 - (-4) = -8 + 4 = -4.

How do you subtract a negative integer from a positive integer?

Back

Subtracting a negative integer from a positive integer is the same as adding the absolute value of that negative integer. For example, 5 - (-19) = 5 + 19 = 24.

What is the final position of an object that starts below sea level and ascends and then descends?

Back

To find the final position, you add the ascent (positive) and subtract the descent (negative) from the initial position. For example, starting at -15 feet, ascending 9 feet, and then descending 12 feet results in -15 + 9 - 12 = -18 feet.

What is the rule for subtracting integers?

Back

The rule for subtracting integers is: a - b = a + (-b). This means you can convert subtraction into addition by changing the sign of the integer being subtracted.

How do you handle subtraction when both integers are negative?

Back

When both integers are negative, you can convert the subtraction into addition of their absolute values. For example, -3 - (-5) = -3 + 5 = 2.
