Adding and Subtracting Integers

Front

What is the result of adding a positive integer to a negative integer?

Back

The result depends on the absolute values of the integers. If the absolute value of the negative integer is greater, the result will be negative; if the positive integer's absolute value is greater, the result will be positive.

Front

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

Back

Subtracting a negative integer is the same as adding its absolute value. For example, 2 - (-10) = 2 + 10 = 12.

Front

What is the sum of -10, 4, and 3?

Back

The sum is -3, calculated as follows: -10 + 4 = -6, then -6 + 3 = -3.

Front

What is the result of -2 + 1 - 8?

Back

The result is -9, calculated as follows: -2 + 1 = -1, then -1 - 8 = -9.

Front

How do you subtract one negative integer from another?

Back

To subtract a negative integer from another negative integer, you add their absolute values. For example, -3 - (-14) = -3 + 14 = 11.

Front

What is the result of adding a negative integer to a positive integer?

Back

The result will be less than the positive integer if the absolute value of the negative integer is less than the positive integer. For example, 4 + (-10) = -6.

Front

What is the definition of an integer?

Back

An integer is a whole number that can be positive, negative, or zero, without any fractional or decimal part.

Front

What is the principle of absolute value in relation to integers?

Back

The absolute value of an integer is its distance from zero on the number line, regardless of direction. For example, |-5| = 5.

Front

How do you determine the sign of the result when adding two integers?

Back

The sign of the result depends on the integers' signs: if both are positive, the result is positive; if both are negative, the result is negative; if one is positive and the other is negative, the result's sign depends on the larger absolute value.

Front

What is the result of 2 - (-10)?

Back

The result is 12, because subtracting a negative is the same as adding a positive: 2 + 10 = 12.
