Marissa subtracting a negative number from a positive number her result was negative is that reasonable explain

It is reasonable because the absolute value of a negative number could be bigger than the positive number.

Step-by-step explanation:

If marissa subtracted - 12 from 7, it would result in a - 5 which is a negative number. The absolute value of - 12 is 12 and 12 is bigger than 7.

Does that make sense?

No, the calculation is not correct.

Step-by-step explanation:

We are given that,

Marissa is subtracting a negative number from a positive number, resulting in a negative number.

For e. g. Let us consider the calculation, 4 - (-3)

Now, 4 - (-3) = 4 + 3 = 7.

So, we see that the resulting number is a positive number.

That is, the minus operation with the negative sign will become addition operation.

Hence, the fact that Marissa is obtaining a negative number after subtracting a positive number by a negative number is not reasonable.
