Question

Simplify:. a) (-7)+(-6)÷2-{(-5)×(-4)-(3-5)}

Answer 1

Hey here is your answer
________________________

$= - 7 + - 6 \div 2 - ( - 5 \times - 4 - (3 - 5)) \\ \\ = - 7 + - 6 \div 2 - ( - 5 \times - 4 + 2) \\ \\ = - 7 + - 6 \div 2 - ( 20 + 2) \\ \\ = - 7 + - 6 \div 2 - 22 \\ \\ = - 7 + - 3 - 22 \\ \\ = - 7 - 3 - 22 \\ \\ = - 10 - 22 \\ \\ = - 32$

Answer 2

Answer:

=> -32

Step-by-step explanation:

As per the data given in the question, we have to simplify the expression

Given that:-

$(-7)+(-6)\div2-[(-5)\times (-4)-(3-5)]$

For solving we have to use the property of BODMAS,

The word 'BODMAS' can be used to remember the sequence in which the various mathematical processes must be completed.

=> B-Brackets

=> O-Of

=> D-Division

=> M-Multiplication

=> A-Addition

=> S-Subtraction

Therefore,

$=>(-7)+(-6)\div2-[(-5)\times (-4)-(3-5)]$

$=>(-7)+(-6)\div2-[+20-(-2)]$

$=>(-7)+(-6)\div2-(20+2)$

$=> (-7)+(-3)-22$

$=>-7-3-22$

$=> -32$

Hence, the required solution is $-32.$
