Simple calculation: 5 + 6 + 7 + 8 + 9 + +100 Why can't we use Gauss's method: (5 + 100) × 95 △ 2


You can use Gauss's method, but
It should be (5 + 100) × 94 △ 2



Calculate 11 out of 12 - (5 out of 12-1 out of 7)


11 / 12 - (5 / 12-1 / 7)
=(11 / 12-5 / 12) + 1 / 7
=6 / 12 + 1 / 7
=7 out of 14 + 2 out of 14
=9 out of 14



4.35 × 99 × 2 × 8.7


4.35*2*8.7*99=8.7*8.7*99=



45 cm to 0.15 km


45 cm vs. 0.15 km
=45 / 100M: 0.15 * 1000M
=0.45:150
=0.03:10
=3:1000
