multiple of 11. if that difference is not a multiple of 11, neither is the original number.
example 1: is 682 divisible by 11?
answer 1: chop the 2 and subtract: 68 – 2 = 66. because 66 is a multiple of 11, so is 682.
example 2: is 1014 divisible by 11?
answer 2: chop the 4 and subtract: 101 – 4 = 97. because 97 is not a multiple of 11, neither is 1014.
example 3: is 32,741 divisible by 11?
answer 3: chop the 1 and subtract: 3274 – 1 = 3273. but is 3273 divisible by 11? apply the rule again: 327 – 3 = 324. some people may see that 324
