X = ( 1+10 ) * 10 / 2 = 11 * 10 / 2 = 110 / 2 = 55
X= (2+20) * 10 /2 = 110
X= (1+19)*10/2= 100
1+2+3+4+5+6+7+8+9+10= (10+1)X10 : 2 = 55
2+4+6+8+10+12+14+16+18+20 = (20+2)x10 : 2 = 110
1+3+5+7+9+11+13+15+17+19 = (19+1) x 10 : 2 = 100

Tính :
A = 1 + 2 + 3 + 4 + 5 + 5 + 6 + 7 + 8 + 9 + 10
A = ( 1 + 9 ) + ( 2 + 8 ) + ( 3 + 7 ) + ( 4 + 6 ) + ( 5 + 5 ) + 10
A = 10 + 10 + 10 + 10 + 10 + 10
A = 60
B = 10 + 20 + 30 + 40 + 50 + 50 + 60 + 70 + 80 + 90 + 100
B = ( 10 + 90 ) + ( 20 + 80 ) + ( 30 + 70 ) + ( 40 + 60 ) + ( 50 + 50 ) + 100
B = 100 + 100 + 100 + 100 + 100 + 100
B = 600
