### Any 4 numbers in order, when the first 2 consecutive numbers are added and then the 3rd and 2nd numbers are subtracted the answer will always be negative 2 .:

Any 4 numbers in order, when the first 2 consecutive numbers are added and then the 3 rd and 2 nd numbers are subtracted the answer will always be negative 2 . Example: 11 + 12 -13 -12 = -2 It needs to be 4 numbers . Step 1 add the first 2 consecutive numbers Step 2 subtract the 3 rd consecutive number Step 3 subtract it again to the 2 nd number. Emman Arrieta

### B3 Alfredo Cruz Jr.:

B3 Alfredo Cruz Jr. Did you know that you can have the same number as the answer for every computation Take the number 9 for instance. You thought it was just a typical number. Well not quite...Have you ever noticed that in the nine times tables, all the answers add up to nine? 1 x 9 = 9 (0 + 9 = 9) 2 x 9 = 18 (1 + 8 = 9) 3 x 9 = 27 (2 + 7 = 9) 4 x 9 = 36 (3 + 6 = 9) 5 x 9 = 45 (4 + 5 = 9) 6 x 9 = 54 (5 + 4 = 9)

Place logo or logotype here, otherwise delete this. Did you know that ? Joshua De villa B4 7-DDS Example: 19x1- 1 9 19x2- 3 8 19x3- 5 7 19x4- 7 6 19x5- 9 5 19x6- 11 4 19x7- 13 3 19x8- 15 2 19x9- 17 1 19x10- 19 0 If you multiply 19 from 1 to 10 then the first or second numbers will be odd numbers. If you look at the numbers that are not underlined if you read it will be the numbers 9 to 0

### Multiplication Table of 9 Trick:

There is a way to solve for the multiplication table of 9 if you are not able to memorize it. Here’s the example: 9x5=? What you need to do is to subtract 1 from the second factor which is 5. so the answer will be 4 . 9x5= 4_? Now to solve for the second digit, the trick is to answer the question “how many do you need to add to the first digit to make it 9?” In this case, the number is 4 so you need to add 5 . This means that the answer for the second digit is 5. 9x5= _5? So if we combine the two digits, we will get the answer which is 45. if we check it, 9x5 is indeed equals to 45. B5 - Dee,Guilbert Sebastian B. Multiplication Table of 9 Trick

### Did you know…….:

Did you know……. That if you multiply 5 to 219,753 your answer will be 1,098,765, and you will get a carry over of 4, 3, 2, 1 consecutively 219,753 5 x 1,098,765 4 3 2 1 Carry over multicant multiplier product B6 JOSE EMMANUEL ELEAZAR

### A fact:

A fact Did you know that there can be 1,000 possible combinations with a 3 digit lock? That is if the digits are allowed to repeat. Choose any digit from 0 to 9 as the first digit. Choose another for the 2 nd and 3 rd digit locks. You are allowed to repeat any of the digits if preferred. With this, the formula is: 10 x 10 x 10 = 1000 Made by: Anjelo Gabriel T. Gacutan 7-Davao Del Sur

### Did you know… Did you know …. :

Did you know … Did you know …. That there is no highest number. If ever you thought of one, you would always think of that number plus one. Surprisingly, there is no such thing as a “Greatest Number". Let’s say the number you picked is, 999 add 1 or more digits to it, after adding it, the number is bigger than the original number. B8 Guzman, Christopher Villamor

### DID YOU KNOW?:

DID YOU KNOW? 12+3-4+5+67+8+9=100 B9 Christian Ellis Jacobsen

### Math Trivia:

Math Trivia If you add the numbers one to ten the middle number in the solution is an even number 1+2=3+3=6+4=10+5=15+6=21+7=28+8=36+9=45+10=55 Edrei Longatang 7-DDS O E O O E E E O O E O O E E E O O E O LEGEND: E= EVEN O= ODD If you connect the odd and even Numbers from end to end it will be Similar to each other

### Counting numbers are formed with 1 figure example 1 (push figure to upper right and add tail pointing to the right) 2 2 (add another curve from the bottom) 3:

By: Mendoza, Daegan Jesse A. 7-DDS B-11 Counting numbers are formed with 1 figure example 1 ( push figure to upper right and add tail pointing to the right) 2 2 ( add another curve from the bottom) 3

### The number of letters in each word in the sentence, “Can I have a large container of donuts right now?” can form the first 10 digits of pi.:

The number of letters in each word in the sentence, “Can I have a large container of donuts right now?” can form the first 10 digits of pi. (3.141592653) Nicdao Lucas Camacho B-12 DDS

### Did you know?:

Did you know? If you add the numbers by itself, the sum of the solutions will be the multiplication table of 2 or it will be always even. 1 + 1 = 2 6 + 6 = 12 2 + 2 = 4 7 + 7 = 14 3 + 3 = 6 8 + 8 = 16 4 + 4 = 8 9 + 9 = 18 5 + 5 = 10 10 + 10 = 20 …. 2,4,6,8,10,12,14 ….. B13 Christopher Mari P. Pinpin

### Math Trivia:

M a t h T r i v i a When you inverse the digits of 1-100 you will have a pattern that repeats /has sequence. LOOK CAREFULLY. EXAMPLE: 001, 999, 899, 799, 699, 599, 499, 399, 299, 199, 099, 989, 889, 789, 689, 589, 489, 389, 289, 189, 089, …. However, the HUNDREDS digits have the sequence of counting (backwards), then the last 2 (TENS AND ONES) digits are always repeating until the counting in the hundreds digits is already 0. G2 ARAGON, PATRICIA AKANE P. 7- DAVAO DEL SUR

### MATH TRIVIA:

MATH TRIVIA If you were to ask to fill a box with a pebble,you start at 8:00 AM and Supposed to finished at Exactly 12:00 NN,What Time are you going to Reach the half of the box?

G12 Maria Concetta Stefania M. Madrid 7-Davao del Sur The number Pi (the ratio of the circumference to the diameter of a circle) can’t be expressed as a fraction, making it an irrational number. It never repeats and never ends when written as a decimal . 3.1415926535897932384626433832795028841971693993751 058209749445923078164062862089986280348253421170679
