Adding Integers on a Number Line

Front

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

Back

The result can be found by subtracting the absolute value of the negative integer from the positive integer. If the positive integer is smaller, the result will be negative.

Front

How do you represent the addition of integers on a number line?

Back

You start at the first integer and move to the right for positive integers and to the left for negative integers.

Front

What is the sum of -8 and 3 on a number line?

Back

The sum is -5, which is found by starting at -8 and moving 3 units to the right.

Front

What does it mean when zero lies between two numbers on a number line?

Back

It indicates that one number is negative and the other is positive.

Front

How do you find the sum of two integers with different signs?

Back

You subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value.

Front

What is the equation modeled by adding 7 and -13?

Back

The equation is 7 + -13 = -6.

Front

What is the result of adding 15 and -25?

Back

The result is -10, as represented by the equation 15 + -25 = -10.

Front

What is the first step in solving an addition problem involving integers?

Back

Identify the signs of the integers involved (positive or negative) and determine how they will affect the sum.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

Front

How can you visualize the addition of integers on a number line?

Back

By plotting the integers on the number line and using arrows to show movement left or right based on the sign of the integers.
