Evaluate the expression. $$ 11-(-23)-77 $$

So in this problem, we're being asked to evaluate the expression, the expression that were given his negative six Q minus. You are. Unfortunately, they tell us that que happens to be two and our happens to be 11. So I'm gonna take the to and substituted in for Q, and I'm gonna take the 11 and I'm gonna substitute it in for our. So that leaves me with six divided negative six, divided by two minus two times 11 or operations says I'm gonna do multiplication division from left to right. So that gives me negative three minus two times 11 which is negative 22 which is equal to negative 25. So when we evaluate the expression we get

We need to simplify the following problems. So we're going to use foil. So we multiply first. So we have 7.8 being multiplied 2 -1.04. Then we have our outers switch colors. Our orders, we have Plus 7.8 times 2.09 i. And we have our winners. We have plus 23 I Being multiplied 2 -1.04. And then we have our last We have plus 23 I being multiplied to 2.09. I As we continue simplifying 7.8 times negative 1.04. This becomes negative 8.112. And we have 7.8 times 2.09. That becomes plus 16.30 to I. And we have 23 times negative 1.04. It's 23 times 1.44. That becomes negative 23.92. I We have 23 times 2.09 and that becomes Positive 48.07 I squared. So we combine our eyes so we have negative 8.112 and then we have 16.30 to -23.9 to this becomes negative 7.618 I. And we have plus 48.7 I squared becomes negative one. So this cleans up to negative 8.11 to -7.618, I -48.07. So we combined the last two terms, so negative 8.11 to minus 48.7 becomes negative 56.18 to minus 7.618 I.

Consider the given expression past. Let us evaluate this multiplication. So it is 13 plus 77 minus six. Student by three in the next district. Let us evaluate this division. So it is 13 plus 77 minus X brightly is too now. Adding the first two numbers. We get 90 minus two. Subtracting this. Forget the answer. This 88.

Seven times are given that are 11 so seven times 11 is 77.
