Hi! I'm helping my little sister's friend with his math homework, and I kinda didn't pay attention in my math class a few years ago and don't really know how to do this.

Can anyone of you help me? Please? Thanks! :)

After some calculating I found out that is there is a loop of numbers (other than 1->4->2->1 loop) that loop can't have an odd-even-odd-even.. pattern. And also if there is a loop of numbers that means that there should be a positive integer solution to 3^n - 2^m = 2^p, which is basically impossible since odd-even is odd, not even. So you cannot have a loop other than 1->4->2->1 or in negative numbers, or I just calculated it wrong, and the numbers can only go to 1 or infinity.

So if you need help on this sort of question

-if 1 kg of sugar is $2

How much is 500 g of sugar?-

It's the price of 500 g of sugar you want to find out, right? Well two 500s are 1kg so 2 divided by 2 is 1.

Why am I dividing 2 by 2? Because 1 kg is $2, and two 500s are 1kg (what I struggle with)

And the answer is $1

At least, I think so :p

Another sum.

-If 1 kg of sugar is $4

How much is 250 g of sugar?-

Four 250s are 1kg and 1kg of sugar is $6 so $4 divided by 4 = $1

I haven't learnt how to do hard sums like that yet :(

There were 10 apples on a tree. Ten people were passing by that tree. Each took an apple but there were 9 apples left. How is that possible?

Maths is sooooooooo hard for me, I know this seems childish but I need help with this

If 1kg of pasta is $12, how much is 250 g of pasta? Please reply as soon as u can tnks!!

Could you tell me the method

The test is in 24 minutes and I have no idea what to doooo, it’s geometry 1, idk if anyone can help😩

Do you think math is hard? Well, it's actually really easy! Let's learn about addition. Addition is easy, follow Ex. 1

Ex. 1:

411

+376

___

787

Did you see what we did? Well we added up the digits and got 787, wow!

Ex. 2:

8,927

+1,009

____

9,936

Wait, what? How is 2+0=3? Well, it's simple, it's because of carrying. Carrying is when the digit that is right 1 digit overflows, where there is not enough digits to use.

Ex. 2.1:

8,927

+1,009

____

9,920

16

____

9,926

It's time for you to practice!

Recently I just realized how dUumB at math I was, always asking for and needing an adult's help. When I stare at the paper/screen, my mind goes blank, which is bad because I have the Ohio State Math Test in a few weeks..........

Example: (first number) x (multiplication times of the first number) (addition of the result) (replacement of the addition of the result) / (second number)

The word "Mathematics" came from the Greek word "máthēma" means 'knowledge, study, learning' , now I wonder what do other subjects came from!

Say for !1 means a^a-1^a-2...4^3^2^1. For example, 3!1 = 3^2^1 = 9. Simple. Right? Say !2 = a^^a-1^^a-2...4^^3^^2^^1. The answer for 4^^3^^2^^1 is vastly very large.
