Aim: What is a mathematical statement?

A mathematical statement is a statment you can reason to decide weteher something is true
or false.

You can tell this is false because pencils and pens do no have viruses.
I had the same problem!!

Example

Adjacent sides, are sides that are next to each other.  This is true because adjacent means
 next to.

Try it out!!
Judge wether these statements are true or false. Circle T for true or F for false.
 
Five plus five equals 10.                        Truth value: T or  F

Twenty times five equals 1,000,000       Truth value:  T or F

Absolute value is the distance from         Truth Value: T or F
 a certain number to 0.

Lunch period starts at 12:47 and ends at 1:29.

In order for a statement to be true while using and both parts must be true.

You can do the handout I gave you or do deltamath for extra credit.

When you are using or either one of the statements can be true or both can be true in order
for the statemnt to be true.

                                                   Conditionals

Conditionals are words to show cause and effect. The words we use are If and Then.

If my grades are higher then 95 in each class then I`ll get $100.

An example of how to put sentences in conditional form is the following:

When it rains. I get my Umbrella.

If it rains then she gets her umbrella.
You just add if infront of the sentence and then for the result.

Try it out!!
Put these sentences in conditional form.

When I finish my homework. I can get pizza.
When Elba behaves in class, she can get a cupcake.

                                               Inverse

Inverse is just adding not in the sentence to make it even with the conditional.

Example: If it is not raining then I do not need an umbrella.

Try It Out!!

Put the following statement in conditional and then in inverse form.

When I am hungry I eat pizza.
