The four studious girls had just finished their 3rd year course of study and has elevated to 4th Year in High School. Special subjects were added.
English 4 - is about Technical Writing
Math 4 - is about Calculus
Science 4 - Physics
Social Studies - World History
P.E. - Recreational PE in the form of games such as : Chess, Scrabble, Tennis, Backgammon
Economics 4- Introduction to Economics
There's no conflict whatsoever until the rest of the 15 students met a new teacher in mathematics.
The teacher who hailed from a private school in England was a little bit obnoxious and with a smile like they are unable to interpret. You know the smirk on her face is prominent.
Calculus is way too different from the way she taught the class. She > Mrs. Dumpling was a famous Mathematician in her country of origin. Instead of teaching them the technique she wants the students to learn the hard way and finding their own ways to tackle every Math problem at hand.
"What kind of teacher is she?" Arnel was heard whispering to Leopold.
Even Joan was heard mumbling incoherently. Is not that she hates Math but numbers have a special meaning for her. Each number has a corresponding symbols and interpretations. For her there are sets of real numbers and imaginary numbers. There are complex numbers and prime and integral numbers. There are perfect and non-perfect numbers. Each number is divisible and can be multiplied by five.
Mrs. Dumpling heard what Joan was mumbling about. The girls could only uttered in disgust. The new teacher stared at them one by one, scowling with bigotry. Then called each one of them to do the board work. They were asked to pin point the rational, integers, natural and irrational numbers on the group of numbers that Mrs. Dumpling has presented in the class.
When its time for Joan to answer some of the numbers displayed on the board, the clever teacher erased whatever is written on the board. She threw the piece of chalk on the floor and told her to do the board work. She asked Joan to show the class an example of Commutative property of Addition and multiplication and associative property of addition.
The poor Joan trembling in fright because Miss Dumpling's rude unruly behaviour and sharp eyes almost piercing through her soul. She is very weird! That what she thought. The whole class knew that Miss Dumpling is bizarre. So bizarre that nobody wants to mess up with her.
Joan tried to retrieve the piece of chalk on the floor that was separated in half.
"Oh no!" the whole class thought it was a bad idea that Joan picked up the broken chalk on the floor.
In front of the black board, Joan started writing and posting the symbols intended for the "property" being asked of her by Miss Dumpling.
Commutative Property Of Addition:
Ex. 3+(4+5) =12
(3+4)+5 =12
Associative Property Of Addition & Multiplication:
Ex. 1+4 = 4+1
4X5 =5X4
"Look at the board class. Can you tell the difference? Do you think Joan is correct?" Miss Dumpling looked at Joan and didn't say a word . After few seconds she asked the class > "Who wants to help her?"
