Is 1458 divisible by 3?
If the sum of a given number's digits is divisible by 3, the number is also divisible by 3. Thus: 1+4+5+8=18 18 is divisible by 3 (18/3=6), ergo is 1458 divisible by 3. Except for the above listed rule of thumb, a calculator comes in handy every now and then.
How do you add or subtract 5 6 8 9 and 10 to equal 1?
There is no sequence of adds or subtracts of 5, 6, 8, 9, and 10 that sum to 1. Check it with this C++ code... for (int i=0; i<32; ++i) { int sum = 0; if (i&1) sum += 5; else sum -= 5; if (i&2) sum += 6; else sum -= 6; if (i&4) sum += 8; else sum -= 8; if (i&8) sum += 9; else sum -= 9; if (i&16) sum += 10; else sum -= 10; cout << i << " " << sum << endl; }
