7.NS.3 Flashcard

Front

What is the difference between high and low temperatures?

Back

The difference is calculated by subtracting the low temperature from the high temperature. For example, if the high is 4 degrees and the low is -7 degrees, the difference is 4 - (-7) = 4 + 7 = 11 degrees.

Front

What is the product of two negative numbers?

Back

The product of two negative numbers is positive. For example, (-2) * (-3) = 6.

Front

How do you calculate overall change in field position when gaining and losing yards?

Back

You write a sum of integers. For example, if a team gains 9 yards and then loses 22 yards, the calculation is 9 + (-22) = -13.

Front

If the temperature is -1°F and it gets 3 degrees colder, what is the new temperature?

Back

To find the new temperature, subtract 3 from -1: -1 - 3 = -4°F.

Front

What is the result of multiplying a negative number with a positive number?

Back

The result is negative. For example, (-4) * 3 = -12.

Front

How do you find the absolute difference between two temperatures?

Back

The absolute difference is found by taking the absolute value of the difference between the two temperatures. For example, |4 - (-7)| = |4 + 7| = 11.

Front

What does it mean when a number is negative?

Back

A negative number is less than zero and represents a value that is below a reference point, such as temperature or debt.

Front

What is the sum of a positive integer and a negative integer?

Back

The sum depends on the values of the integers. For example, 5 + (-3) = 2.

Front

How do you represent a loss in yardage in a mathematical expression?

Back

A loss in yardage is represented as a negative integer. For example, losing 10 yards is represented as -10.

Front

What is the significance of zero in integer operations?

Back

Zero is the additive identity, meaning any number plus zero equals the number itself. For example, 5 + 0 = 5.
