1001
What is the average of all the numbers 1 to 1000?
500.5 Because: 1+2+3+.......998+999+1000 Add 1 to 1000 equaling 1001. This makes a pair. There are 500 more of these so 500 pairs. So 1001x500= 500500 Finally divide it by 1000 because there are 1000 numbers. (1000-1=999+1=1000) Concluding the answer to be 500.5 :)

Easier way than what?I presume you mean long multiplication of 999 by 999, adding 998 and adding 1.One way:999 = 1000 - 1 ⇒ 999 x 999 + 998 + 1 = (1000 - 1) x (1000 - 1) + 998 + 1= 10002 - 2 x 1000 + 1 + 998 + 1= 1000000 - 2 x 1000 + 1000= 1000000 - 1000= 999000Another way:998 + 1 = 999 ⇒ 999 x 999 + 998 + 1 = 999 x 999 + 999= 999 x (999 + 1)= 999 x 1000= 999000

The sum of four consecutive 3 digit numbers is3990 what are the 4 numbers?
You can solve this problem algebraically: (X) + (X+1) + (X+2) + (X+3) = 3990 4X + 6 = 3990 4X + 6 - 6 = 3990 - 6 4X = 3984 4X/4 = 3984/4 X = 996 Therefore, the 4 numbers are 996, 997, 998, 999 996 + 997 + 998 + 999 = 3990
