00:00Mik-Mik, ready ka na ba sa math challenge ko?
00:02Ready, ready, ready na po!
00:05Confident ha? I believe magagawa mo yung challenge, Mik-Mik.
00:08Oo, bago yun, maituturo muna ako sa inyo para maging matinik kayo sa pag-solve.
00:14Papakita ko kung paano mag-multiply by 9 gamit ang iyong mga daliri sa kamay.
00:20Okay, so let's start. Charlie will help me out here.
00:23Una, taas, dalang kumay, so that's 10 fingers. Tama ba? 10 ba ang daliri mo?
00:28Tarang 10 naman po.
00:30Okay, sige. Okay, so kung 9 times 1, baba ng the first 1 kasi 1 eh, times 1.
00:35So we have 1, 2, 3, 4, 5, 6, 7, 8, 9. The answer is 9, di ba?
00:41Okay, up again. 9 times 2, ibababa ni Charlie yung second na daliri.
00:47So we have here 1 and then 1, 2, 3, 4, 5, 6, 7, 8.
00:54So 1 and 8 is?
00:5618.
00:57Mik-Mik?
00:5818, 4.
00:59Okay, very good. Okay, up again.
01:019 times 3, ibababa ni Charlie ang third finger.
01:05So we have 1, 2, and then 1, 2, 3, 4, 5, 6, 7.
01:112 and 7 is?
01:1327.
01:14Tama ba? 9 times 3 is 27. Tama, Mik-Mik?
01:17Apo.
01:17Okay, very good. Okay.
01:19Okay, 9 times 4, Charlie.
01:22Okay, 4 finger down.
01:241, 2, 3, and then 1, 2, 3, 4, 5, 6, 3, and 6 is?
01:3236.
01:3236.
01:3336. So 9 times 4 is 36. Tama?
01:36Tama po.
01:36Okay, game. Okay, got it. I think nag-gets niyo na. I believe ours, nag-gets niyo na.
01:39Now, gawin na ating random.
01:41Okay, I'm gonna give you a problem, a formula to solve.
01:46And then, gamitin niyo yung technique na ito para ma-try niyo i-solve.
01:52Mik-Mik, ikaw ang sasagot.
01:53Si Ate Charlie ang mag-assist sa'yo.
01:56Sige po.
01:577 times 9.
02:00Same lang naman, di ba? Kasi 9 times 7, 7 times 9 is the same thing. Random.
02:04So, binaba ni Ate Charlie ang 7. Ilan yan?
02:086, tsaka 3, 63.
02:11Alright. Very good.
02:13Okay, okay. Next.
02:169 times 8.
02:187, tsaka 2, 72.
02:2172 is correct.
02:23Alright, okay.
02:24Ano pa?
02:259 times 5.
02:279 times 5.
02:294 at tsaka 5, 45.
02:3245. Very good, Mik-Mik.
02:34Di ba? Ang dali lang, di ba?
02:36Thank you, Charlie.
02:38Mik-Mik, gets?
02:40Gets po. Ang galing niyo, Kuya Chris.
02:42Paano nga nawo-work yung multiplication by 9 gamit ang daliri?
02:47Good question.
02:48That's because multiplying by 9 is almost similar sa pag-multiply by 10 sa daliri.
02:53Ang formula niyan is 10 times N, parentheses, tapos may minus 9.
02:59At yung binaba mong finger is yung minus 9 sa equation.
03:04Basta from 1 to 10, pwedeng isolve.
03:07Tama.
03:18Tama.
03:18Tama.
