Given the 'new to programming', I'm gonna forgive you for a couple of elements. Using using namespace will bite you in the end, though, until you learn about namespaces you should not worry about that.
Posted on April 13, by Passy Image Source: We have one for you a bit later in this lesson. Word Problems need to be turned into Algebra Expressions so that we can do mathematics on them, and work out number answers.
Or write a Computer App that gets the answer. If the word problems only have numbers, then it is easy to translate them, once we have practiced doing a few word problems. Consider the following real life example. Mathematicians rewrite word situations into Algebra Expressions to make them simpler and more direct to work with.
Algebra Expressions are needed in computer apps which are written to process real world situations. Computers use letter variables and mathematical symbols in the Algorithms in their programs, rather than full word English sentences.
Translation Tips for Word Problems The following translation tables help convert word problems into Algebra Expressions. Look for the following key words and phrases when reading through word problems.
This will help form the Algebra equation for the word problem. The following words in a sentence indicate that Adding is taking place. The following words in a sentence indicate that Subtraction is taking place. We need to be careful when translating Subtraction words. The following words in a sentence indicate that Dividing is taking place.
The following words in a sentence indicate that Multiplying is taking place. The following words in a sentence need to be translated into an equals sign.
Whenever we get a word problem to convert into Algebra, we can use these translation tables to help us work out what mathematical symbols we need to use to replace the words. Here are some simple examples.Algebraic Expressions: An algebriac expression is made of numbers,operations and one or more variables.
In general the algebraic expressions are simplified using the following properties. Algebraic Expressions questions for your custom printable tests and worksheets.

Age 11 to 14 Challenge Level: Charlie took a sheet of paper and cut it in half. Then he cut one of those pieces in half, and repeated until he had five pieces altogether.
A factor in this case is one of two or more expressions multiplied together. Factoring an expression means breaking the expression down into bits we can multiply together to find the original expression. The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression.
Instead of "8 plus 9" (with two given numbers), you would see, "a number plus 9". Algebra Expressions are needed in computer apps which are written to process real world situations.
