The number is 12.
12 ÷ 2 = 6
6 - 4 = 2
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.
7
it means multiply the the number in the ones place by two and use that number to subtract
34?
Let X = the number X + 2 = 3X+6 subtract x from both sides 2 = 2X +6 2X + 6 = 2 subtract 6 from both sides 2X = -4 divide by 2 X = -2 = the number
2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.
you can multiply add subtract divide make into a fraction or percentage or squuare it or cube it ortry to maki it using base 2

If you take the number 969 and subtract the 9 remainder you get 960. Because the number is even you can divide it by 2. 969/2 = 480R9. :)
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.
quotient means to divide, so the quotient of 2 is to divide by 2. difference means to subtract, so subtract by 5
no because if you subtract it as you have seemed to show here then you get an even number which makes it possible to divide by 2

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.
