20 x 10 = 200

20 + 10 = 30

I don’t know, sorry. The calculator on my computer isn’t working. Try using that and calculating these possible answers:

21 x 9 = ?

22 x 8 = ?

23 x 7 = ?

24 x 6 = ?

25 x 5 = ?

26 x 4 = ?

225 – 15 x 15

14 x 16 = 224

let x and y be the two numbers

30 = x + y

z = xy

y = 30 – x

z = x(30 – x)

z = 30x – 2x^2

the maximun product is the y value of the vertex and the answer should be 225

15 x 15 = 225
