**OK, so what do we do it the numbers are too big for a number line?**

**How do we know if the answer will be positive or negative?**

**Let's look at one we did with small numbers:**

**Look at these numbers without their signs: 3 and 7**

**Which is bigger? The 7.**

**So, the answer will have that guy's sign... which is positive!**

**Look at this one:**

**Look at these and ignore the signs: 2 and 5**

**Who's bigger? The 5.**

**What's his sign? Negative. So, the answer is negative!**

**Let's do one with bigger numbers:**

**First, will the answer be positive or negative?**

**30 and 53... 53 wins... The answer is positive.**

**Now, we need to get the number part of the answer.**

**Here's what you do:**

1 | Ignore the signs |

2 | Take the biggest numberand subtract off the smaller one |

** **

**And we leave it positive.**

**Hey, don't panic! This is easy and you'll get used to it. We just need to do more of them!**
