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.
