Hi all, Given this question and I am lost as to what it means. Any help would be appreciated. Let a = 68, b = 33, and n = 3, a. Verify that 3 | ( 25 – 19 ). Thanks

Hello, 3 | (25-19) means that 3 divides (25-19), or in other words that 25-19 is a multiple of 3. Does this help you go through this question ?
This simply would mean that 6 is a multiple of 3. A statement like 3 | (25-18) would then be incorrect, and would not be written this way. Thanks heaps
