Thank you so much..I'm a corporate secretary student and we need the gt function for calculating PVAF and discounting but I wasn't able to do it coz I accidentally bought this model of the calculator, I was looking for somebody who was facing the same problem and here you are. What do we do when we need to subtract a value, say whatever your answer was to the second row , we need to subtract that from the total of the rest? E.g (243×23)-(345×2)+(227×98)
Yes. You can use (243×23=5589) and then you add 5589 with M+ and then if you also want to subtract it, you can use M-. Since 243×23=5589 in M+ 345×2=690 5589-690= press M+ to add 5589 and then press M- to subtract 690. M+5589 M-690 5589-690=4899 And then finally you add again (227×98=22,246) and then you press M+ 22,246 and your final grand total result is =27,145 1. M+ 5589 2.M-690=4899 3.M+22,246=4899+22,246=27,145 Thats how it works with this operation (243×23)-(345×2)+(227×98) M+ 5589 then M- 690 then M+22,246 and then Press MRC=27,145
@@calistavaz1478 @Calista Vaz As I have seen about pviaf. The formula of it is PVIFA = (1 - (1 + r)^-n) / r. Haven't thought about that calculation yet but I hope this video helps ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I1klFNWATjk.html
