• When adding and subtracting, you have two signs. adding and subtracting. Obviously in word problems are not going to say add 2+1 or subtract 2-1. Most times in word problems it will say, Sally had 2 apples and Johnathon had six. If Johnathon eats four of his apples how many will there be? What you have to do is subtract, but first you have to add. so add 2+6, and then subtract 4 from your total. In word problems there will be key words. for example, take away, how many more, how many fewer, more, and less. BE CAREFUL: some cases in word problems, more could mean less, and less could mean more.
