Question

How much lower is Checkpoint 4 -186 than Checkpoint 5 2,888?

a) 2,702
b) 2,474
c) 3,074
d) 2,702

Answer 1

To determine how much lower Checkpoint 4 is in comparison to Checkpoint 5, subtract Checkpoint 5's value from Checkpoint 4's value, considering the negative sign of Checkpoint 4. The difference is 3,074, indicating that Checkpoint 4 is 3,074 units lower than Checkpoint 5 and making option (c) the correct answer.

Step-by-step explanation:

To find how much lower Checkpoint 4 is than Checkpoint 5, you would perform a subtraction with the values given for each checkpoint. Checkpoint 5's value is 2,888 and Checkpoint 4's value is -186. The operation would be 2,888 - (-186).

Here are the steps for this calculation:

1. Write down the initial values of both checkpoints.
2. Change the subtraction of a negative number to addition.
3. Add the two values together.

So, adding a negative number is equivalent to subtracting its absolute value. Therefore, we calculate 2,888 + 186, which equals 3,074.

The difference is 3,074, which is the absolute value of the numbers when subtracted. Option (c) is the correct answer: 3,074.
