Sarah : Do you remember what is Acid, Alkaline and Neutral?
Rina : Of course! It is so easy!
Sarah : Are you sure?
Rina : Yup!
Sarah :Okay, here's a question, name three subtances for Acid, Alkaline and Neutral.
Rina : Um..Ahah! Acid is Lime, orange juice and shampoo. Alkaline is Rice and umm..
Sarah : See! You still didn't understand about Acid, Alkaline and Neutral!
Rina : But I only can't remember the subtances only.
Sarah : The question will appear at the examination, you know that?
Rina : Yeah! I almost forgot! But, what should I do? I still can't remember the subtances!
Sarah : Okay, le's go back to the question I asked. You said that the subtances of Acid is lime,
orange juice and shampoo. Shampoo is not Acid. It is Alkaline. And, you also said that
Alkaline is rice. That is also wrong! Rice is Neutral.
Rina : Oh! But, how do we know what is Acid, Alkaline and Neutral?
Sarah : Acid taste sour and change blue litmus paper to red. Alkaline taste bitter and change red
litmus paper to blue. Neutral is tasteless. There is no colour changes at the litmus paper.
Rina : Oh! Thanks for the tips! And now, I could remember it easily!
Sarah : You're welcome!

Mathematic info
Korang nak tahu apa maksud matematik? Ketahuilah matematik dengan lebih mendalam..
Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions.
Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, and the social sciences. Applied mathematics, the branch of mathematics concerned with application of mathematical knowledge to other fields, inspires and makes use of new mathematical discoveries and sometimes leads to the development of entirely new mathematical disciplines, such as statistics and game theory. Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind, although practical applications for what began as pure mathematics are often discovered
