7 times 6 is 42. If you subtract two, you get 42-2= 40.

32
42 less subtract 21 from 63 , that is to say, 63-21 is 42 so it is 42 less. 63-21 = 42
Once because 7 - 49 = -42 but you can subtract 7 from 49 seven times
n=9. Because n+42=51. Subtract 42 from both sides and n=9
multiply by 2 then subtract 6
Take the current year and subtract 42 from it. For example, if the year was 1962, then subtracting 42 from it would equal 1920.
Answering with the current year (2014) as of this answer: 1972. All you have to do is subtract 2014 and 42, which gives you 1972.
