Answer:

0

Explanation:

Given the difference:


-36.673+39.999

In front-end rounding, we consider the number with the largest place value.

In -36.673, the number with the largest place value is 3.

The digit after 3 us 6, so we round up as follows:


-36.673\approx-40

Likewise, In 39.999, the number with the largest place value is 3.

The digit after 3 us 9, so we round up as follows:


39.999\approx40

Therefore:


-36.673+39.999\approx-40+40=0

The diffrence is 0 using front-end rounding.
