Question

Suppose that a spreadsheet contains the following values.
A1 6
B1 -4
C1 2
D1 3
Determine the value of cell E1 if it contains the following formulas.
a) +A1 + B1 E1= 2 got that one right
b) +4*A1 + 5*B1 got that one wrong
c) +C1*(A1 +3*B1) got that one wrong
d) +A1+...+D1 or sum(A1.. D1) got it right. What could I have done wrong.
Could you please help me.

Answer 1

(b) 4(6) + 5(-4) = 24-20 = 4
(c) 2(6 + 3(-3)) = 2(6-9) = 2(-3) = -6

when asking what you did wrong, it's a lot better if you show what you did, so we can figure that out.
