1 00:00:01,570 --> 00:00:06,490 OK, so our ad flashcard works now we want to create a subtract one. 2 00:00:06,520 --> 00:00:12,700 So what we can just do here is kind of copy all of the stuff from our ad. 3 00:00:14,320 --> 00:00:24,060 Functio, and so these two functions add and add, correct, and we can just kind of above here paste 4 00:00:24,070 --> 00:00:28,720 pasted in again and instead let's call this subtraction. 5 00:00:30,430 --> 00:00:33,070 And let's change this one up here. 6 00:00:35,350 --> 00:00:42,040 Subtract and we could just come through here and kind of, you know, spot check, change these. 7 00:00:42,040 --> 00:00:45,280 So subtract output answer correct. 8 00:00:45,520 --> 00:00:46,980 Let's leave all of these for now. 9 00:00:48,200 --> 00:00:51,770 Let's call this subtract answer. 10 00:00:52,760 --> 00:00:56,690 And then subtract correct label. 11 00:00:58,200 --> 00:01:00,810 And subtract. 12 00:01:02,640 --> 00:01:08,940 Correct label again and add answer will change just to subtract answer. 13 00:01:10,010 --> 00:01:15,200 And then add flash will change this to subtract Lasch. 14 00:01:18,180 --> 00:01:24,270 OK, and then this function, we'll call it subtract instead of add. 15 00:01:25,510 --> 00:01:28,660 And then instead of ad frame, this is subtract frame. 16 00:01:29,960 --> 00:01:36,910 And I think these can stay the same, so add Flash will change this to subtract flash, change this 17 00:01:37,130 --> 00:01:38,590 to act. 18 00:01:38,750 --> 00:01:43,910 I'm just going to copy the word subtract so I can just paste this in boom. 19 00:01:44,240 --> 00:01:46,760 And here we need to change it as well. 20 00:01:47,540 --> 00:01:50,210 And let's just look through here, ok. 21 00:01:50,280 --> 00:01:51,850 OK, that looks good. 22 00:01:52,620 --> 00:01:53,930 Well, let's call this. 23 00:01:55,290 --> 00:01:58,140 Subtract, answer and. 24 00:01:59,910 --> 00:02:04,170 Before bomb that that. 25 00:02:06,230 --> 00:02:07,670 That very scientific. 26 00:02:09,630 --> 00:02:17,840 We're almost done add frame, subtract frame, so this we want to change this to subtract. 27 00:02:17,840 --> 00:02:18,620 Correct. 28 00:02:21,270 --> 00:02:24,240 All right, and subtract button. 29 00:02:25,630 --> 00:02:27,670 And a couple more here. 30 00:02:29,270 --> 00:02:33,260 Add to subtract, basically, we're just changing all the ads to subtract. 31 00:02:33,740 --> 00:02:39,890 All right, so let's save this and give this a run to see if that possibly worked. 32 00:02:41,600 --> 00:02:43,480 So we want subtract. 33 00:02:43,490 --> 00:02:45,290 Oh, and that is still. 34 00:02:46,390 --> 00:02:47,020 No good. 35 00:02:47,060 --> 00:02:55,230 So all right, so let's go down here to our frames and subtract frame. 36 00:02:56,200 --> 00:02:57,900 We need to take this off. 37 00:02:58,160 --> 00:02:59,510 I want this color anymore. 38 00:03:00,130 --> 00:03:00,970 OK, so. 39 00:03:01,970 --> 00:03:07,670 Subtract frames come up to our subtract, oh, we have to subtract submenu right here. 40 00:03:12,160 --> 00:03:14,470 So we need to get rid of that. 41 00:03:17,260 --> 00:03:20,050 Because we put it up here instead. 42 00:03:23,090 --> 00:03:26,320 OK, so let's save this and give this a run now. 43 00:03:30,640 --> 00:03:35,010 OK, so three plus 10 is obviously not what we want, but let's just see if it worked. 44 00:03:36,090 --> 00:03:42,480 No, it did not add answer is not defined, so we missed some some things oh, let's look and see what 45 00:03:42,480 --> 00:03:48,210 line that was line 18 so it can come up here to line 18. 46 00:03:53,260 --> 00:03:57,840 Subtract answer, and we're going to have to fiddle with this logic as well, because this is still 47 00:03:57,840 --> 00:04:03,870 doing Ed. But let's just run this again to see what else we missed. 48 00:04:04,140 --> 00:04:05,610 I will surely miss something else. 49 00:04:05,620 --> 00:04:06,720 So eight plus nine. 50 00:04:07,900 --> 00:04:10,690 Incorrect 18, correct? 51 00:04:10,720 --> 00:04:11,630 OK, so that's working. 52 00:04:11,830 --> 00:04:18,580 Now we need to fiddle with the logic and this shouldn't take but a second, so let's go to our subtract 53 00:04:18,580 --> 00:04:20,470 correct and are now are correct. 54 00:04:20,470 --> 00:04:26,860 It should be number one, minus number two, and then everything else needs to be changed accordingly 55 00:04:26,860 --> 00:04:27,780 inside of here. 56 00:04:27,790 --> 00:04:31,780 So let's go minus there and minus there. 57 00:04:32,890 --> 00:04:35,710 OK, so let's save this, that should do it, I think. 58 00:04:39,520 --> 00:04:43,750 OK, so subtract zero plus we missed something here. 59 00:04:45,510 --> 00:04:54,990 So here, subtract flash config, this needs to be minus and also in our subtract right here for subtract 60 00:04:54,990 --> 00:04:59,530 flash label, this also needs to be minus OK. 61 00:05:00,840 --> 00:05:03,810 I feel pretty good now, I think maybe maybe we got it all. 62 00:05:05,250 --> 00:05:09,540 Let's so subtract four minus four is zero. 63 00:05:10,640 --> 00:05:17,750 Correct, for minus four equals zero, two, minus four is negative two, correct to minus four equals 64 00:05:17,750 --> 00:05:19,310 negative to ten, minus six. 65 00:05:19,310 --> 00:05:20,990 One hundred and forty three. 66 00:05:20,990 --> 00:05:24,680 Incorrect, ten minus six equals four, not one hundred and forty three. 67 00:05:24,890 --> 00:05:25,310 All right. 68 00:05:25,310 --> 00:05:27,040 So that was pretty simple. 69 00:05:27,110 --> 00:05:31,580 Some copying and pasting, a little tweaking here and there, but that's pretty much all there was to 70 00:05:31,580 --> 00:05:35,150 that in the next video will knock out the multiplication one.
