Some problems are difficult to solve.But there are a lot of number expressions that can help.For example, if we put two and two together , we might com e up with the right answer.We know that two heads are better than one.It is always better to workwith another person to solve a problem.Some problems have only one solution.You cannot be of two minds over this.But with any luck , we can solve the problem in two shakes of a lamb' s tail.In other words, we could have our answers quickly and easily. Sometimes we can kill two birds with one stone.That is , we can complete two goals with only one effort or action.But we must remember that two wrongs don' t make a right.If someone does something bad to you, you should not do the same to him. If you are going out with your girlfriend , or boyfriend , but you don' t want another friend to go a long on your date, you can just say to your friend : two' s company , three' s a crowd. When I was a young child in school , I had to learn the three R' s.These important skills are reading , writing and arithmetic.These three words do not all start with the letter " R".But they have the sound of " R".My teacher used to give three cheers when I did well in maths.They gave praise and approval for a job well done. Some of my friends were confused and did not understand their school work.They were at sixes and sevens.In fact , they did not care if they finished high school.But they were happy when they completed their studies and graduated from high school.They were in seventh heaven.They were on cloud nine.Nine times out of ten students who do we'll in school find good jobs.Some work in an office doing the same things every day at nine-to-five jobs.You do not have to dress to the nines , or wear your best clothes , for this kind of work. If you solve a problem without any difficulty , you can also say that you can do it_.
