'How to Know if you can Divid by Seven''' You might be thinking this is stupid any number is clearly divisible by seven. But this is how to know if it can be divided with no decimals. The rule is simple and clear the reason it works not so much. this rule will NOT work on any number less than 100, only on numbers greater. Think of any number (ex. 12,324,444,412,242), is this number evenly divisible by 7, who knows. In order to find out you first must do this. Take every counting digit after the tens place and write then out as if they were all in the ones place and being added (ex.1+2+3+4+4+4+4+4+1+2+2=31) Then it that number is greater than 99 repeat until it is 99 or less. Once it is 99 or less add the number to the tens place and back in your original number (ex. 31+42=73) because that number is not divisible by 7 the original number is not to.
