I can help you with this math problem. To find the value of the expression $$30:(-5)-21:(-4-3)$$, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction.

First, you need to simplify the expression inside the parentheses. $$-4-3=-7$$

Next, you need to perform the division operations. $$30:(-5)=-6$$ and $$21:(-7)=-3$$

Finally, you need to subtract the two results. $$-6-(-3)=-6+3=-3$$

Therefore, the value of the expression is $$-3$$. I hope this helps.Ответь+подробно.++Знайдіть+значення+виразу+30:(-5)-21:(-4-3)+
