Question: Why can`t we get rid of maths? It`s so difficult.
Answer:
Would life really be all that simple without maths? Well, there wouldn't be equations or any problems to solve. This means no proper dimensions when building something, even a table to fit in a particular corner of a room, because you wouldn't know how to measure. You wouldn't be able to design buildings based on precision.

There really wouldn't be any currency, just trading one thing for another maybe.

No maths means no measuring, which means no delicious cakes or ice-creams because we wouldn't know how to measure. Plus, you wouldn't be able to design machines for baking delicious chocolate cakes.

Izma, let's admit that Maths is the mother of all sciences.
Physics and chemistry wouldn't exist without maths. Houses would fall on our heads if there wasn't such a thing called Maths; moreover, maths equals logical reasoning, so without maths we won't have logic and without logic we would be all messed up.

Question: Solve the following equation: x(x-9)=0
Answer:
x=0 or x=9

If you substitute zero in the equation, you get 0(0-9) and this equals 0.
If you substitute 9 in the equation, you get 9(9-9) and this equals 9x0 which is again zero.

Question: When a person drinks alcoholic drugs, why does he get dizzy and sleepy?
Answer:
Most of the effects of alcohol that people experience during intoxication are due to how it affects the brain. One of the most rapid effects of alcohol is on the central nervous system (CNS), which controls a range of vital body functions including the organs. When one is intoxicated the alcohol interferes with the CNS's ability to analyse sensory information. This results in the typical symptoms of being drunk. Typical symptoms include:

- Decreased motor coordination and balance
- Slurred speech
- Blurred visions
- Sweating
- Loss in judgment
- Dulling one's sensation of pain (The dulling of pain is why alcohol was used in the past as an aesthetic).

Answer:
As per the policy of the Cambridge International Examination (CIE), you are not allowed to appear in both Urdu A and Urdu B in the same examination session. You have to make a choice between the two. I would suggest that you opt for Urdu A.

Question: What is an alloy?
Answer:
An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals from which they are formed. This makes them more useful than the pure metals. For example, alloys are often harder than the metal they contain. Alloys contain atoms of different sizes, which distort the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal.

Question: Which has more heat energy, a hot cup of tea or glacier? Why?
Answer:
It's all about the sheer volume of an ice berg compared with the volume of the liquid in a cup of tea. Although the tea is a lot hotter, the ice berg itself has heat energy, even below zero degree C. That's because it's not at absolute zero or -273'C.

Using absolute zero as a base, or degrees Kelvin, the iceberg will be at around 260-270 Kelvin. The tea may be around 360-370 Kelvin, 100 degrees warmer - but this difference is overwhelmed by the sheer size of the iceberg.

Question: I hate tashree nagari. Help me, it's too lengthy; can't we write tashree in short form?
Answer:
The word tashreeh has been derived from an Arabic word sharah, which means ‘to explain in detail’. Therefore, while doing the tashreeh of a verse or poem, you are required to write a detailed explanation. So, unfortunately it can’t be done in short form.
Good Luck!

Question: what is the technic of proffesional colour mixing?
Answer:
Izaa, I do not understand your question. What do you mean by colour mixing? Mixing colours on the paper or canvas? Or mixing colours in water (for dyeing)? What types of colours – watercolours, oils, pastels, markers or pencils?

‘Techniques of painting’ is a vast subject. Nevertheless, if you identify the specific area, I can be more helpful. .
