### Did You Know That? …:

Did You Know That? … G1 Bianca Isabel M. Adia When you multiply a number by 10 you would get the same number you multiplied it with and the last digit would be 0. 218 x 10 = 2,180 527 x 10 = 5,270 713 x 10= 7,130 421 x 10 = 4,210 *also applicable with other powers of 10 21 x 1000 = 21,000 546 x 100 = 54, 600

8 1 6 3 2 6 4 1 28 2 56 5 12 1 ,024 2 ,048 4 ,096 My Math Trivia In this math trivia, I have “experimented” or tried to see a pattern in adding 8 to itself and adding the sum to itself too... Repeating and repeating the process like: 8+8=16+16=32+32=64 and so forth. What I saw is that in every ten numbers, the first digits repeat. And I have theorized that this pattern would also be compatible in other numbers. Ex. 4+4=8+8=16+16=32 and so forth or like others number like 2, 3, 5, etc. 8, 1, 3, 6, 1, 2, 5, 1, 2 and 4 By Sheina Balayo | 7 - Basilan 8 ,192 1 6,384 3 2,768 6 5,536 1 31,072 2 62,144 5 24,288 1 ,048,576 2 ,097,152 4 ,194,304 8 ,388,608 1 6,777,216 3 3,554,432 6 7,108,864 1 34,217,728 2 68,435,356 5 36,870,912 1 ,073,741,824 2 ,147,483,648 4 ,294,967,296

### DiD you know that…:

### PowerPoint Presentation:

9876543210 0123456789 TRIVIA Multiplying numbers 1-10 by 9 can be also in this way: 1 x 9 = 2 x 9 = 3 x 9 = 4 x 9 = 5 x 9 = 6 x 9 = 7 x 9 = 8 x 9 = 9 x 9 = 10 x 9 = At the first set of digits (with the pink background) write 0-9 (0 1 2 3 …) downwards. Then at the second set of digits (with green background) write 9-0 (9 8 7 6 …) downwards. The answers will be the same if you multiply the numbers 1-10 by 9. ☺ G6 Kizha Gabutan 7-Basilan
