4. When traveling abroad many of the units used are different. One of the most common is the unit of temperature namely Fahrenheit versus Celsius. The conversion between the 2 temperatures is as follows. c=}(F-32) (a) Using the formula above convert 50° Fahrenheit to Celsius. (b) This conversion formula is very useful if you are given Fahrenheit, but less useful if you know a Celsius temperature. Solve the above equation for Fahrenheit, F, and then convert 50° Celsius into Fahrenheit. Is there a large difference in Fahrenheit and Celsius?

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
