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.

Front

What is the result of subtracting a larger positive integer from a smaller positive integer?

Back

When you subtract a larger positive integer from a smaller positive integer, the result is negative. For example, 9 - 15 = -6.

Front

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.

Front

In the context of sea level, how do you represent positions above and below sea level?

Back

Positions above sea level are represented as positive integers, while positions below sea level are represented as negative integers.

Front

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.

Front

What is the result of subtracting two negative integers?

Back

When you subtract two negative integers, you can think of it as adding their absolute values. For example, -16 - (-11) = -16 + 11 = -5.

Front

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.

Front

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.

Front

What is the significance of the number line in understanding integer subtraction?

Back

The number line helps visualize integer subtraction. Moving to the left represents subtraction, while moving to the right represents addition.

Front

How do you determine the position of an object after multiple movements in relation to a reference point?

Back

To determine the final position, you need to account for all movements by adding and subtracting the distances from the reference point.
