Hello,
I have a math question in regard of the Project network node. in the question the following information is given :
ES:21 LS: 37 LF:39
And the question is to calculate EF, Duration and Float.
I started the problem with calculating the Duration with the following formula LS-LF +1 (37-39 +1 ) and the answer is 3 days.
I got the answer wrong because I was following the Math rule and calculated -1 and I should have been doing 39-37 +1 = 3. But by switching the 37 and 39, I'm not following the math formula anymore... and this is what i don't grasp.
Is anyone able to provide some clarity and explain why we are aloud switch number .
Thank you,
