Answer :

To simplify the expression [tex]\(-1 \times 10 + 10 \times 10\)[/tex], follow these steps:

1. Identify and perform the multiplications first as per the order of operations, which states that multiplication should be done before addition and subtraction.

2. Calculate [tex]\(-1 \times 10\)[/tex]:
[tex]\[ -1 \times 10 = -10 \][/tex]

3. Calculate [tex]\(10 \times 10\)[/tex]:
[tex]\[ 10 \times 10 = 100 \][/tex]

4. Add the results from the two multiplications:
[tex]\[ -10 + 100 = 90 \][/tex]

5. Thus, the simplified result of the expression [tex]\(-1 \times 10 + 10 \times 10\)[/tex] is:
[tex]\[ 90 \][/tex]

So, the final answer is 90.
