Question

7+7÷7+7×7-7=?
A.0 B.50 C.8 D.56 ​

Answer 1

Answer:

First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.

The expression 7 + 7 ÷ 7 + 7 × 7 – 7 has no parentheses or exponents, so we evaluate multiplication and division.

7 ÷ 7 = 1

7 × 7 = 49

This means

7 + 7 ÷ 7 + 7 × 7 – 7

= 7 + 1 + 49 – 7

Now we can evaluate the addition and the subtraction from left to right.

= 8 + 49 – 7

= 57 – 7

= 50

The correct answer is 50.

Answer 2

$\bf\huge\gray{ANSWER}$

$\large \text\pink{Follow the Bodmas rule }$

$\sf \red{ = >7 + 7 \div 7 + 7 \times 7 - 7 }$

$\sf \purple{( \div ) \: is \: performed }$

$\sf{ = > 7 + 1 + 7 \times 7 - 7}$

$\sf \purple{( \times ) \: is \: performed }$

$\sf{ = > 7 + 1 + 49 - 7}$

$\sf \purple{( + ) \: is \: performed }$

$\sf{ = > 57 - 7}$

$\sf \purple{( - ) \: is \: performed }$

$\large\boxed{ = > 50}$

$\bf \huge\green{Therefore}$

$\large\text{Option b) 50 is correct option}$
