Question

Simplify 102 × 7 0 + 2 3 × 3 1 − 5 0 × 3 0 + 7 1 × 3 1​

Answer 1

• $5652.$As per the data given in the question, we have to find the value of the expression.

         Given data:-$102\times70+23\times31-50\times30+71\times31.$

         To find:- The value of the expression.

         Solution:-

• To solve the above equation we will follow the BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

   where,

                  $B=bracket\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { Division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

 So by the  above equation, we get

                $=102\times70+23\times31-50\times30+71\times31.\\=7140+713-1500+2201\\=7853-3701\\=4152.$

    Hence the value will be $4152.$

Answer 2

Given,

$102\times70+23\times31-50\times30+71\times31$

We have to simplify this given expression by using BODMAS rule

B-bracket

O-of

D-division

M-multiplication

A-addition

S-subtraction

We have to apply BODMAS to solve the given expression

$102\times70+23\times31-50\times30+71\times31$

$= 7140+713-1500+2201$

$= 10054-1500$

$= 8554$

Therefore, the answer is $8554$.
