Beremx:that's multiplication mod7 |
Re: Can Someone Help Me Out With This? by dejt4u(m): 9:26am On Aug 18, 2020 |
Beremx:21. 5 0 2 = 5 × 2 = 10 (converting 10 to a mod7 number is 10 - 7 = 3) Correct answer is 3 (option C) 22. 3 0 6 = 3 × 6 = 12 (converting 12 to a mod7 number is 12 - 7 = 5) Correct answer is 5 (option E) 23. 6 0 ? = 5, (this 5 is in mod7 which is 7 + 5 = 12) So, 6 × ? = 12, ? = 12 ÷ 6 = 2 Correct answer is 2 (option B) 24. ? 0 4 = 2, (this 2 is in mod7 which is 7 + 2 = 9) So, ? × 4 = 9, ? = 9 ÷ 4 = **** (this doesn't work, then we move to higher multiple of mod7. That is, we use 14 instead of 7. If it doesn't work again, then we move to 21, 28, 35, e.t.c) ? 0 4 = 2, (this 2 is in mod7 which is 14 + 2 = 16), So, ? × 4 = 16, ? = 16 ÷ 4 = 4 Correct answer is 4 (option D) 4 Likes |

dejt4u:is mod7 the same as base 7? |
Re: Can Someone Help Me Out With This? by dejt4u(m): 9:40am On Aug 18, 2020 |
Beremx:No. They are not the same.. Mod7 means that no number can be up to 7. The maximum we can see is 6. That is; 1 in mod7 is 1 2 in mod7 is 2 3 in mod7 is 3 4 in mod7 is 4 5 in mod7 is 5 6 in mod7 is 6 7 in mod7 is 0 8 in mod7 is 1 9 in mod7 is 2 10 in mod7 is 3 11 in mod7 is 4 12 in mod7 is 5 13 in mod7 is 6 14 in mod7 is 0 15 in mod7 is 1 16 in mod7 is 2 17 in mod7 is 3 18 in mod7 is 4 19 in mod7 is 5 20 in mod7 is 6 21 in mod7 is 0 22 in mod7 is 1 23 in mod7 is 2 e.t.c 1 Like |

dejt4u:Wow!! The quantitative questions was gotten from a common entrance past questions. The mod7 should be for secondary school abi? Please which topic in math does it fall in? |
Re: Can Someone Help Me Out With This? by dejt4u(m): 10:00am On Aug 18, 2020 |
Beremx:basic operation I think. I was introduced to this topic in one of my early days in further mathematics class in SS1 |
Re: Can Someone Help Me Out With This? by Beremx(f): 10:07am On Aug 18, 2020 |
dejt4u:oh okay. This is what someone sat down and told Primary six to solve in Common Entrance? It is well. Thanks for your timely response. I really do appreciate |
