3 means you won $3.
-4 means you lost $4.
3+(-4) means you won $3 and then lost $4, a net loss of $1. This is why 3+(-4)=-1.
Make sense?

The key to understand decimals is to think about money, as we use money every day. For example, 0.05 means 5 cents, and 1.1 means a dollar and 10 cents.

Unit 4 Lesson 1: Introduction to Decimals

Unit 4 Lesson 2: Add/Subtract Decimals

Unit 4 Lesson 3: Multiply/Divide Decimals

Unit 4 Lesson 4: Decimals and Fractions

Unit 4 Lesson 5: Square Root

Unit 4 Lesson 6: Mean, Median and Mode

Rate and proportion are used every day. For example, a car drives at 50 miles per hour, which is an example of rate.
If the owner of a property worth $300,000.00 pays $2,000.00 in property tax, how much tax should the owner of a property worth $400,000.00 pay? We can solve this problem with proportion.
Proportional thinking is critical in later math lessons.

Unit 5 Lesson 3: Unit Conversion

We use percent almost every day: A product is 30% off; the town's population increased by 30%; you just got a 5% raise, ... It's obvious how important percent is.
