数学很重要，我们几乎每天都会用到数学。我们如何运用数学呢？我们会数东西。一个房间里有多少人？我们怎么知道？我们要数一数。或者我们必须买两件东西,一共要多少钱？一件4美元，另一件3美元。我们把这两个价钱加起来，所以4美元加3美元等于7美元，总价是7美元。
Math is important. We use it almost every day. How do we use it？ We count things. How many people are in a room？ How do we know？ We count them. Or maybe we have to buy two things. How much do they cost？ One is $4. Another is $3. We add them together. So $4 plus $3 is $7. The total is $7.
