Question 789050
looks like you are evaluating the formula
P(1+r)n  by substituting the following values
12,875,255(1+0.003)13
note that this implies that r is .3 %
parenthesis imply "do me first" and then multiplication and division from left to right
12,875,255 * 1.003 *13
1.2913880765e7 * 13
note that e7 means 10^7
1.67880449945e8
