For the numbers 1 thru 9, the result is always 5. In fact, the result is 5 for any integer, and if you change the wording slightly to say 'add this to the original number plus 1' instead of 'add this to the next higher number' the result is 5 for ANY complex number. Here's why: Number picked: x Next higher number (for integers) or Number picked plus 1 (for any other sort of number): x + 1 Add them: x + x + 1 = 2x + 1 Add 9: 2x + 1 + 9 = 2x + 10 Divide by 2: x + 5 Subtract starting number: x + 5 - x = 5. Every tiime.

Divide the new number by the original number, subtract '1', and multiply by 100.
Subtract the difference from 10 and divide by 2. This gives the lower number. Now add 1.4 to that and you get the higher number. If you find that beyond you try 4.3 and 5.7
Whichever number is higher you subtract the other one from it, and keep the sign of the higher number
the answer will always be 5
Divide the number by 5 and subtract the answer from the original number...

If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

You subtract some other number, or you divide by some other number, etc.
The midpoint between 113 and 284 is 198.5. To get the number you subtract 113 from 284 and then divide by 2. The number you get, you can add it to 113 or subtract it from 284 to get the correct answer.
25. work backwards. take 37 ADD(instead of subtract) 13 to it. then take 50 and divide it by two.
Pick any number. Multiply by 6. Add 13. Subtract 7. Divide 3. Divide 2. Then subtract by the original number you chose. Your result will always be 1. Tell a friend to mentaly multiply their age by 2. Tell them to add 14 then divide 2. Ask your friend what number they currently have. Now, you mentally subtract 7 from the number they tell you, then you'll know your friend's age.
you subtract the numbers then he higher number to start out with is the awnser. example: negative 3 - positive 7= 3-7=4 the higher number is 7 so i is positive. the final answer is positive 4
