4, 4+4=8-5=3
An easy way to do this is to manipulate the original number and make sure to "undue" all the manipulations you did. For example: pick any number, add 3, subtract 2, subtract the number you started with, you have 1. Example explained: x + 3 - 2 - x = 1. More complex example: pick any number, multiply by 2, add 4, subtract 2, divide by 2, subtract 2, add 4, subtract the number you started with, you have 3. Explained: (((x * 2) + 4 - 2) / 2) - 2 + 4 - x = (2x + 2) / 2 + 2 = x + 3 - x = 3.
To get the right answer. If you add 1/3 and 1/4, you might not be as successful as when you add 4/12 and 3/12.
Subtract the numerator Subtract or add the numerator Subtract or add the numerator ex: 3/4-1/4=2/4 or 1/2 ex: 5/8 + 1/8= 6/8 or 3/4
you add 3 and 4 then subtract 1
IT looks like the operations is "add 4 subtract 3, add 5 subtract 2, add 6...". So the next step would be to subtract one. That would make the next number 11.
You add up 4,3 and 4 and then you subtract that by eight
Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.
7
4. Reverse the process to find the number: 7 is added to the product of 3 and a number to get 19. The last thing done is add 7; the reverse process of add is subtract, so subtract 7, leaving: The product of 3 and a number is 19 - 7 = 12. The reverse process to multiply (product) by 3 is divide, so divide by 3, leaving: a number is 12 ÷ 3 = 4

-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
