Question

10 + 21 + 32 + 43 + 54 + (-54 ) + (-43) + ( -32) + ( -21) + (-10)

Answer 1

0

Explanation:

To simplify the given expression, you can group the positive and negative numbers together:

(10 + (-10)) + (21 + (-21)) + (32 + (-32)) + (43 + (-43)) + (54 + (-54))

Now, perform the addition within each group:

(0) + (0) + (0) + (0) + (0)

The result is 0. So, the simplified value of the expression is 0.
