True enough. I cannot understand why b=5. Does = mean "equals" or something else? Why does being inside parenthesis make it 5?
"starting w/ a=4, b =5 because it is inside parenthesis
a * b = a - 3b
becomes
4 * 3
4 - 3(3) per the def of * and substituting
4 - 9 regular arithmetic
-5"
From Porschegal’s explanation, “We are given that a * b= a - 3b. To evaluate 4*3, we must recognize that a corresponds to 4 and b corresponds to 3.”
Here, for some reason, we are to recognize that b "corresponds" to 3. Why?
So b has some relationship to 5 (equals 5?) and "corresponds" to 3. WTH does that mean??
