What js the value of the expression 10 -16÷2

Answers

16÷2=8 then 10_8=2 the answer is 2

Final answer:

The value of the expression '10 - 16 ÷ 2' is determined by first performing the operation of division, then subtracting that result from the remaining number. The value of this mathematical expression is 2.

Explanation:

The subject of your question is Mathematics, specifically an arithmetic order of operations problem. This question falls under the Middle School level. The expression given with the question is 10 -16÷2.

In mathematics, when you are solving such expressions, the order of operation matters. The precedence rules that define the order of operations state that division and multiplication (whichever appears left to right) have higher precedence than addition and subtraction. This rule is often remembered with the acronym PEMDAS, which stands for Parentheses, Exponentiation, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Using these rules, we first perform the operation of division (16 ÷ 2). The result of that division is 8. The next step is to subtract that result from 10. So, it will be 10 - 8 and we obtain a value of 2 for the expression.
