Count the number of tens:
10 tens
Add up Ten-Groups
Ten-Groups = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10
Ten-Groups = 100
Count the number of ones:
0 ones
Add this to the ones for our total:
100 = 0 Hundreds + 100 Tens + 0 ones
100 = 0 + 100 + 0

Divisibililty Check for 11
Σ odd digits - Σ even digits = 0
or 100 is a multiple of 11
Sum the odd digits:
100
1 + 0
Odd Sum = 1
Sum the even digits:
100
0
Even Sum = 0
Take the difference:
Δ = Odd Sum - Even Sum
Δ = 1 - 0
Δ = 1
Divisibility Check:
Because Δ / 11 = 9.0909090909091:
Then 100 is NOT divisible by 11
