Question 216781: my 4th grade grandson is learning pre-algebra??? I only had algebra in 9th grade way back in the 60's and can't remember how to do any of it. How do I explain "Find the value of a x 3 for each value of a? Examples are a=2, a=5, a = 1 and a =4. I need help understanding so I can explain it to him. Thanks, Becky

You can put this solution on YOUR website! The problem gives you an "equation":
a x 3
.
Then, they want to know the result if:
a=2, a=5, a = 1 and a =4
Basically, replace 'a' with the value and multiply.
.
Set up a table.
1st column: a
2nd column: a stuffed into the equation
3rd column: resultant value
.
a | a x 3 | result
=======================
2 | 2 x 3 | 6
5 | 5 x 3 | 15
1 | 1 x 3 | 3
4 | 4 x 3 | 12
