Помогите решить примеры (3870-870)+(2170+30)/10,7900/100+(4800+200)*100

Answer 1

3000+2200/10=3000+220=3220
79+5000*100=79+500000=500079

Answer 2

I can help you solve the math problems. Here are the steps and the answers:

- For the first problem, $(3870-870)+(2170+30)/10$, we need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. First, we simplify the expressions inside the parentheses: $(3000)+(2200)/10$. Then, we perform the division: $(3000)+(220)$. Finally, we add the two terms: $3220$. So, the answer is $3220$.

- For the second problem, $7900/100+(4800+200)*100$, we also follow the order of operations. First, we simplify the expression inside the parentheses: $7900/100+(5000)*100$. Then, we perform the division and the multiplication: $79+500000$. Finally, we add the two terms: $500079$. So, the answer is $500079$.
