Do you know Definitions? Bushi is learning!

Bushi is learning definitions these days! Learn with him!  

Definitions-

Prime Numbers-

The numbers having only two factors are called Prime Numbers. Those factors are 1 and itself. Examples-2,3,5,7,9,11,13,19 etc.

Composite Numbers-

Numbers having more then two factors are called Composite Numbers. Example- 4,6,8,10,12,14,16,57 etc.

Twin Prime Numbers-

If the difference between the pair of Prime numbers is 2, then they are called Twin Prime Numbers. Example- 3 and 5 because 3-5=2

Co- prime numbers (or) Relatively Prime numbers-

If 1 is the only common factor for 2 numbers then that two numbers are said to be relatively prime or co-prime numbers. Example-12 and 13. The factors of 12 are- 1,2,3,4,6,12. The factors of 13 are- 1,13. 1 is the only common factor for 12 and 13. Hence 12 and 13 are relatively prime.

Multiples and Factors-

The numbers 2,4,6,8,10… are formed by multiplying natural numbers with 2.These numbers are Multiples of 2.We know that 3x3=6.Two is said to be factor of 6. 6 is said to be a multiple of 2.

Thought -

“Some mathematician has said pleasure lies not in discovering truth, but in seeking it.”

Maths Riddle-

How can you add eight 8's to get the number 1,000? (only use addition) 

 Answer-

The key to this math riddle is realizing that the one       place must be zero.
888 +88 +8 +8 +8 =1,000 

Bushi is a mathematician!

Do you know that whenever I study tables in-front of Bushi, he always repeats after me like-

Me-2 x 1 = 2

Bushi- tu an zaa tu

Me- 16 x 7 = 122

Bushi- sisteen seva untuntu 

In that way he speaks and our Bushi knows tables from 1 to 12 (he is just a parrot!)

Now he is learning tables from 13 to 20 with me! Help with us! Here are the tables from 13 to 20=

13 × 1 = 13 13 × 2 = 26 13 × 3 = 39 13 × 4 = 52 13 × 5 = 65 13 × 6 = 78 13 × 7 = 91 13 × 8=104 13 × 9=117 1×10=130
14×1=14 14×2=28 14×3=42 14×4=56 14×5=70 14×6=84 14×7=98 14×8=112 14×9=126 14×10=140
15 × 1 = 15 15 × 2 = 30 15 × 3 = 45 15 × 4 = 60 15 × 5 = 75 15 × 6 = 90 15 × 7=105 15 × 8=120 15 × 9=135 15×10=150
16 × 1 = 16 16 × 2 = 32 16 × 3 = 48 16 × 4 = 64 16 × 5 = 80 16 × 6 = 96 16 × 7=112 16 × 8=128 16 × 9=144 16×10=160
17×1=17 17×2=34 17×3=51 17×4=68 17×5=85 17×6=102 17×7=119 17×8=136 17×9=153 17×10=170
18 × 1 = 18 18 × 2 = 36 18 × 3 = 54 18 × 4 = 72 18 × 5 = 90 18 × 6 = 108 18 × 7 = 126 18 × 8 = 144 18 × 9 = 162 18 × 10 =180 19 × 1 = 19 19 × 2 = 38 19 × 3 = 57 19 × 4 = 76 19 × 5 = 95 19 × 6 = 114 19 × 7 = 133 19 × 8 = 152 19 × 9 = 171 19 × 10 =190 20 × 1 = 20 20 × 2 = 40 20 × 3 = 60 20 × 4 = 80 20 × 5 = 100 20 × 6 = 120 20 × 7 = 140 20 × 8 = 160 20 × 9 = 180 20 × 10 =200               Thought- Failure is success if we learn from it.
