Well, isn't that just a happy little math problem! Let's think about it together. If we call the number x, we can create two equations: 8x + 12 = 2x + 120. By solving this, we find that x equals 9. So, the number you're thinking of is 9. Happy calculating!
First, multiply the original number by 10. Then multiply the original number by 2. Add the two answers that you got and you have just multiplied by 12. For Example: 7x12=(7x10)+(7x2) 70+14 84
Multiply the number of feet times 12, and add to the inches.
12
32
A negative multiplied by another negative will always give a positive answer. E.g. -4 x - 3 = 12
A negative number e.g 3 times -4 = -12 Do the normal sum then add in the minus (when timing) :)
You get 50.
