Question

simplify
{15 x 115-(-3)} (4 - 4) + 3{5+(-3) * (- 6)}
​

Answer 1

Solving the first bracket of (-3)(4–4) = (-3)(0) = 0

=> 15-(0)-3{5+{(-3)×(-6)}

Now we see 0 is devided by something in (0)÷3{5+{(-3)×(-6)} which should be equal to zero 0

So,

=> 15–0 = 15 (Ans)

Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

${15 \times 115-(-3)} (4 - 4) + 3{5+(-3) \times (- 6)}$

$\bold{\underbrace{15×115+3}}$×0+3{5+(-3)×(-6)}

_____________________________________

Note :when we Multiply or divide any value with zero the resultant will be also zero.

and When zero is added to any value gives the same value ,There is no effect on the value.Value remains same.

let's Understand with another example:

1.)25×0=0

2)10+2×5×0=0

3)0/25=0

4)$\frac{10 + 2 \times 5}{0} = 0$

____________________________________

=>0+3{5+18}

=>0+3×23

=>0+69=69

Concept used:

• $\bold{\:+\:-=\:-}$
• $\bold{\:-\:-=\:+(but\:sign\:of\:+)}$

Calculation:

115

×15

_____

575

115×

_____

1725

______

Now multiply 1725 to zero =1725×0=0

-3×-6=18

0+3(5+18)=3×23=69
