Question

Start with the equation 0-2 = 0 to explain why -4.2 must equal -8.

Drag descriptions and equations to the table to complete the explanation.

Answer 1

When subtracting 2 from 0, the result is 0. Similarly, subtracting 2 from -4.2 will result in a negative number less than -4.2, such as -8.

Step-by-step explanation:

In the equation 0-2=0, the operation being used is subtraction. When subtracting 2 from 0, we are essentially taking away 2 from 0, resulting in 0. Since -4.2 is less than 0, subtracting 2 from -4.2 will move us even further away from 0, resulting in a negative number that is less than -4.2. Therefore, -8 is the correct answer.
