Answer to Pi[x]er?

hey look I'm not doing my homework i just practice for the CPT TEST because i dont remeber many things that i learned when i was at school. ok so think before you talk.

without using calculator after raised up the number :

175321 * 175321 = 30737453041

In Oder to ensure that the number is divisible to 11, the formula is sum up all the odd places number to subtract sum of all even places number.

( sum all the odd place' number) - (sum all the even place'number)

if : answer = 0 or multiple of 11, mean the number can be fully divisible by 11.

But: if the answer is not equal to 0 or not the multiple of 11. the answer from the subtraction will be the remainder.

Solving the problem: 3 0 7 3 7 4 5 3 0 4 1

odd place numbers : 3 + 7 + 7 + 5 + 0 + 1 = 23

even place numbers: 0 + 3 + 4 + 3 + 4 = 14 -

remainder 9
