Question

What is the flaw in the solution of
$\frac{100 - 100}{100 - 100} = 2$

Answer 1

so easy
...
I think u know this form,
a²-b²=(a-b)(a+b)
..
so take 100 as 10²
..
(100-100)/(100-100)
..
(10²-10²)/100-100
$\frac{(10 - 10)(10 + 10)}{10(10 - 10)}$
....$\frac{10 + 10}{10}$
$\frac{20}{10} = 2$

.....
hope it helps u

thank u
