Answer 2

Answer: 20

Step-by-step explanation:

Given: Expression as {(-10) ÷2} * (-4)

To find: The value of the above expression?

Solution: To find the solution to the above expression let's have a look at the rules of BODMAS because we are going to use the laws and rules of BODMAS in this question to solve the expression.

The BODMAS rule is an acronym used to remember the order of operations to follow when solving expressions in mathematics. It stands for B - parentheses, O - order of powers or roots (in some cases "z"), D - division, M - multiplication, A - addition, and S - subtraction. It means that expressions with multiple operators need to be simplified from left to right only in that order. We solve parentheses first, then powers or square roots, then division or multiplication (whichever comes first from the left side of the expression), and finally subtraction or addition, whichever is on the left.

BODMAS, referred to as the order of operations, is the sequence to perform operations on an arithmetic expression. Mathematics is about logic and some standard rules that make calculations easier for us. So BODMAS is one of those standard rules for simplifying expressions that have multiple operators.

In arithmetic, an expression or equation involves two components:

• Numbers
• Operators

Now look at the expression given to us,

{(-10) ÷2} * (-4)

Firstly open the innermost brackets({}) that contain -10 and 2 in it which gives us the expression as -10÷2 which is equals to -5

Now the expression has resolved to {-5}*(-4)

open both the brackets for further calculations which gives us the expression as,

$-5*-4$ which gives us the result as $20$

Hence the answer to the whole expression is 20
