Division & Fractions & Decimals

   



AND and OF
 

      In math, as in English, AND is a signal that at least two ideas are involved. Very often these ideas also involve addition, but not always.

      In math, as in English, OF is a signal that information about 1 item is going to be stated.

      See "Of & And."



"Write the code & algebraic expression/equation" Notes & New Homework
 
    Write the code & algebraic expression/equation then check the answer.   Note: Your browser may print the answers with spaces that are not ment to be there.
 
1.) the sum of a number and two
 
2.) the product of two more than a number and two less than that number
 
3.) half the result when a number is doubled then increased by 3
