Answer 2

To calculate the expression 998*992-988*982+978*972-968*962+...+18*12-8*2, we can break it down into smaller parts and then sum them up.

Let's start by calculating the first part of the expression: 998*992-988*982.

998 multiplied by 992 is equal to 990016, and 988 multiplied by 982 is equal to 970216. Subtracting these two results, we get 19800.

Next, let's calculate the second part of the expression: 978*972-968*962.

978 multiplied by 972 is equal to 949536, and 968 multiplied by 962 is equal to 931216. Subtracting these two results, we get 18320.

Continuing this pattern, we can calculate the remaining parts of the expression and sum them up.

Now, let's calculate the third part of the expression: 968*962-958*952.

968 multiplied by 962 is equal to 932416, and 958 multiplied by 952 is equal to 911616. Subtracting these two results, we get 20800.

Next, let's calculate the fourth part of the expression: 958*952-948*942.

958 multiplied by 952 is equal to 911616, and 948 multiplied by 942 is equal to 894216. Subtracting these two results, we get 17400.

Continuing this pattern, we can calculate the remaining parts of the expression and sum them up.

Finally, let's calculate the last part of the expression: 18*12-8*2.

18 multiplied by 12 is equal to 216, and 8 multiplied by 2 is equal to 16. Subtracting these two results, we get 200.

Now, let's sum up all the calculated parts of the expression:

19800 + 18320 + 20800 + 17400 + ... + 200
