Count the number of hundreds:

3 hundreds

Add up Hundred-Groups

Hundred-Groups = 100 + 100 + 100

Hundred-Groups = 300

Count the number of tens:

6 tens

Add up Ten-Groups

Ten-Groups = 10 + 10 + 10 + 10 + 10 + 10

Ten-Groups = 60

Count the number of ones:

5 ones

Add this to the ones for our total:

365 = 300 Hundreds + 60 Tens + 5 ones

365 = 300 + 60 + 5
