Question

What is the result of -21÷(-2-5)+(-14)+6×(8-4×3) ? I need help
​​

Answer 1

negative 36

Explanation:

You will useva method known as BODMAS its a principle of combined operations like the one above in mathematics.

B-brackets

O-Of (multipliction) ;commonly used when fractions are involved

D- division

M- multiplication

A- addition

S- subtraction

Working out:

first we will solve the brackets then rewrite the question with the answer obtained

-2-5=-7

8-4×3= minus 4

new question :

-21÷-7+-14+6×minus 4

Next is division since there is no of

-21÷-7=3

Negative divided by negative equals positive

3+minus 14 +6×minus 4

Now do multiplication 6×minus 4= minus24

3+ minus 14+minus 24=minus 36

Answer 2

Combined calculation:

Answer:

`\begin{gathered} \sf - 21 / (2 - 5) + ( - 14) + 6 * (8 - 4 * 3) = \\\sf- 21 / (2 - 5) + ( - 14) + 6 * (8 - 12) = \\ \sf- 21 /( - 3) + ( - 14) + 6 * ( - 4) = \\ 7 + ( - 14) +( - 24) = \\ \sf 7 - 14 - 24 = \\ \sf - 7 - 24 = \\ \sf \green{ - 31}\end{gathered}`

When we solve combined calculations, we must first separate into terms when there is an addition or a subtraction.

Then, we solve the operations respecting the hierarchical order of the operations:

• First we solve the powers and roots.
• Then divisions and multiplications.
• Finally, addition and subtraction.

If the calculation has grouping signs, they must be solved in the following order:

• Parenthesis.
• Brackets.
• Keys.
