(913÷326)−[(−1+53)−9×3]=
95/3
97/3
96/3
98/3
We have to use BODMAS rule for the calculations. So,
(913÷326)−[(−1+53)−9×3]==6−[23−27]=6−[−793]=973
source (i)89+−116(ii)3+5−7(iii)1−12 and 2−15(iv)−819+−457(v)79+3−4(vi)526+11−39(vii)−169+−512(viii)−138+536(ix)0+−35(x)1+−45(xi)−516+724
Without adding find the sum
(i) 1 + 3 + 5 + 7 + 9
(ii) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19
(iii) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23
