How is iron a power resource?

Answer:

1. -30 should be added to get -15
2. 12 -99 we will get -23

Answer: 1st question = (-30), 2nd question = (-35)

Step-by-step explanation:

1st question = 15 + (-30) = -15

There are many ways to explain this, the easiest one is the number line method(which you should be able to do) but I am gonna tell you this in a normal applicable way.

Think of 15 as your account balance. You are owing the bank 15 rupees so it is written as minus(-) 15. Here, minus(-)15 means that you still have a debt of 15 rupees even after paying off the current 15 rupees from your bank account. So that means the current 15 added to the amount you still owe them after you have already paid your current balance, which should be 15 as shown equals to 30, implying that you have to owe them 30 rupees for the leftover to be (-15).

This applies to the second question as well.

The above explanation seems really weird but believe me after you understand that properly, you will definitely be able to do this kind of questions yourself or you can use the simplest and easiest number line method which is available in the most basic teachings as I have already written on the top few lines.

My dear brother,

I am safe and sound and hope you will also be enjoying a healthy life with the blessings and grace of Allah Almighty.

I am very glad to know that you have passed your F.Sc examination with flying colours. Now, you must think about your future career. My advice may benefit you. You know, there is a great dearth of doctors in our country. It is your national duty to fill up this gap. You are quite good at science subjects. Your result shows that you can prove an asset to the medical profession. By becoming a doctor, you can serve the suffering humanity in a better way.

Moreover, it is a handsome and gentle way of earning money. You are fit for hight studies in medicine. A doctor commands great respect in society. He leads a comfortable life. He is very close to the sufferings of people. In this way, he can earn the pleasure of God by serving the poor and down-trodden people. Try to get admission to some medical college.

With best wishes

Yours truly,

X.Y.Z
