3.7 × 6 / 5 + 103 / 5 / 6 0.5 × (3 / 5 + 6 / 25) it is urgent to calculate simply
Is there a simple calculation method for 2468.98100
If you just take a few numbers and divide them by two, they are even numbers, and all of them are even numbers
How to calculate 2 + 4 + 6 + 8 +... + 98 + 100 in a simple way?
Because 98 + 2 = 100, 96 + 4 = 100
So the above question = 100x25 = 2500
-How about 2 + 4-6 + 8. - 98 + 100
(-2+4)+(-6+8)+.. +(-98+100)=2*25=50
2:1 by 3:2 by 4:3 + 4:2 by 6:4 by 8:6 ellipsis + 200:100 by 300:200 by 400:300
1/2*2/3*3/4+2/4*4/6*6/8+.+100/200*200/300*300/400
=1/2*2/3*3/4+1/2*2/3*3/4+.+1/2*2/3*3/4
=1/4+1/4+.+1/4
=1/4*100

A simple calculation of 4 / 5 (5 / 8-1 / 2) and 1 / 2
4 / 5 △ [(5 / 8-1 / 2) / / 1 / 2]
=4 / 5 △ [(5 / 8-1 / 2) × 2]
=4 / 5 △ [5 / 8 × 2-1 / 2 × 2]
=4 / 5 ÷ [5 / 4-1]
=4 / 5 / 1 / 4
=4 / 5 × 4
=16 out of 5
