Therefore, the value of the expression is -82.8.

Step-by-step explanation:

To solve this expression, we need to follow the order of operations, which is:

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

There are no parentheses or exponents, so we move on to step 3:

10 - 6 + (16 ÷ 5) - (9 x 10)

= 10 - 6 + 3.2 - 90 (dividing 16 by 5 gives us 3.2)

= -82.8
