Given :The given numbers are 35, $-40$, 6.To do :We have to add 35 and $-40$ and subtract it from 6.Solution :Sum of 35 and $-40$ is,$35+(-40)=-(40-35) = -5$Subtracting $-5$ from 6 is,$6-(-5) = 6+5 = 11$.The resultant number is 6.

Butterfly method for comparing fraction:In Butterfly method, we multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction. It is similar to cross multiplicationSuppose you want to compare the fractions frac{1}{3} + frac{2}{5}31​and52​. ... Read More
