Answer 3

I can help you with math problems. The expression you entered is:

$$1+1*1-1:1+(1+1-1):1+1-(1+1+)$$

To find the numerical value, we need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. We also need to remember that division and multiplication have the same priority, and so do addition and subtraction. In these cases, we perform the operations from left to right.

First, we simplify the parentheses. There are two pairs of parentheses in the expression:

$$(1+1-1)$$

and

$$(1+1+)$$

The first one is equal to 1, and the second one is invalid because it ends with a plus sign. Therefore, the expression cannot be evaluated. We can write it as:

$$1+1*1-1:1+1:1+1-(1+1+)$$

If we remove the last plus sign, the expression becomes valid and we can continue to simplify it. The next step is to perform the multiplication and division operations from left to right. There are three such operations in the expression:

$$1*1$$

$$1:1$$

and

$$1:1$$

The first one is equal to 1, the second one is equal to 1, and the third one is also equal to 1. We can write it as:

$$1+1-1+1+1-1+1$$

The last step is to perform the addition and subtraction operations from left to right. There are six such operations in the expression:

$$1+1$$

$$1-1$$

$$1+1$$

$$1-1$$

$$1+1$$

and

$$1-1$$

The first one is equal to 2, the second one is equal to 0, the third one is equal to 2, the fourth one is equal to 0, the fifth one is equal to 2, and the sixth one is equal to 0. We can write it as:

$$2+0+2+0+2+0$$

The final result is the sum of these numbers, which is 6. Therefore, the numerical value of the expression is 6, if we ignore the last plus sign. Otherwise, the expression is invalid and cannot be evaluated.Ответь+подробно.++Найдите+числовое+значение+выражения+1+1*1-1:1+(1+1-1):1+1-(1+1)+
