You already know the number is -3.
Four less than three times the sum of a number and four.
So, four less than will be at the end of the formula. The beginning of the formula is 3 times.
So it looks like this so far
3( )-4 Now let's look at "the sum of the number (-3) and 4.
So this is how it looks now
3(-3+4)-4
Remember, do inside the parenthesis first, then multiply, and lastly your subtraction.

I would suggest looking up a converter chart, I don't know all of them but I can help with some.
For yards to feet you have to divide by 3 because there are 3 feet in a yard.
For lbs, it's 16 oz in a pound, so divide by 16.
For miles to yards you divide by 1760 because there are 1760 yards in a mile.
I hope this helps a little bit.
