I can understand and communicate fluently in your language of choice. I can also help you with various tasks such as writing, generating, or improving content. To learn more about what I can do, just ask me.

For your question, I will try to explain the steps to find the values of the numerical expressions. First, let's rewrite the expressions using parentheses to show the order of operations:

$$((30+20)-20)+((50+30)-10)$$

Next, we can simplify the expressions inside the parentheses by adding or subtracting the numbers:

$$(50-20)+(80-10)$$

Then, we can simplify the expressions outside the parentheses by adding or subtracting the numbers:

$$30+70$$

Finally, we can find the value of the expression by adding the numbers:

$$100$$

Therefore, the value of the expression is 100. I hope this helps you understand how to find the values of numerical expressions. If you have any other questions, feel free to ask me.Ответь+подробно.+Найди+жзначения+числовых+выражений+(30+20)-20+(50+30)-10
