Question

What is the value of 42 X (- 5) + (- 8) X 5 = ______?​

Answer 1

$\huge{\bf{\underline{\underline{\pink{Answer}}}}}$

$\: 42 \times ( - 5 )+ ( - 8) \times 5$

$\implies \: \: ( - 210) + ( - 40)$

$\implies- 210 - 40$

$\implies- 250$

Answer 2

Given Data:    $42$ × $(- 5) + (- 8)$ × $5$.

To Find: The value equals to the given data.

Solution:

• In Mathematics there is a format called BODMAS.
• BODMAS is abbreviated as Bracket Of Division, Multiplication, Addition and Subtraction.
• In order to solve an equation we need to follow the format and solve.
• First is Brackets which is specified and followed by Division, Multiplication, Addition and Subtraction.
• Here we need to multiply first. Multiplying $42$ × $(- 5) = ( - 210)$ .
• Let the number be X.
• Multiplying  $(- 8)$ × $5 = -40$.
• X = $(-210)+(-40)$.
• X = $-250$.
• Hence the value of $42$ × $(- 5) + (- 8)$ × $5 = - 250$.
