Math Question Help Needed
My son has a problem in his math book that has not shown itself in previous lessons and I was hoping someone here could help.
If a * b = a - 3b and a # b = 2a+3b, evaluate the expression (4 *3) # 5.
In a problem like this, what does # mean? He has several of these types of problems in the next few lessons and I want to make sure we understand it fully. I have looked in my teacher's book and it has a poor explanation.
TIA
