3. kellyp73

these ar so confuseing

In a case as simple as this, I think the best thing was to give the answer.

5. Compassionate

Kellyp, what don't you understand?

6. kellyp73

how do you write an equasion?

7. kellyp73

i have a hard time learning math dont unerstand it

8. Compassionate

An equation has an equal sign in it. x = 1<-- equation x + y = 2 <-- equation 2y - 5 = 9 <-- equation

9. kellyp73

thirteen multiplied by h is onehundred and four

10. Compassionate

lolwut

11. kellyp73

i have to write it as an equasion

12. Compassionate

13 x h = ??? What does 13 times h equal? 13 x y = (Put the number here)

13. kellyp73

thats were im haveing issues what h means

14. Compassionate

h is a variable. Basically, h can be any number. For example, 13 x h = 103 Just replace h with any number you want 13 x 1 = 103 13 = 103, this is false because 13 does not equal 103.

15. kellyp73

really its very confuseing

16. Compassionate

You're having troubles with letters, right?

17. kellyp73

yes i do not understand this kind of math.. i am trying to learn it but it is hard

18. Compassionate

This type of math is called algebra. It is very simple. Please, view this link to understand what these, "letters," mean. They can be confusing at first, but they're actually very easy to understand. http://www.mathsisfun.com/definitions/variable.html

im gona look at it i quite school when i was young and quite before i learned it so now im havein a hard time

21. Compassionate

You'll do fine. This type of math is really easy to get a hang of. Please look at both the links I posted.

22. kellyp73

i am def gona

23. Compassionate

Let me know once you've viewed those links and if you understand or not.

24. kellyp73

ok the one that i was wondering about thirteen multiplied by h is one hundred and four can u explain that one

25. Compassionate

Okay, so lets focus on the first part of this word problem. It's saying thirteen is being multiplied by h. Basically, h is a variable. H can be any number, we don't know what h is currently, but we do know it's being multiplied by h. So, "Thirteen multiplied by h," would be: 13 x h <-- Now this is equal to 104. 13 x h = 104 <-- Because the equation tells us 13 times h is equal to 104.

26. kellyp73

how do you come up with h is equal to 104 ?

27. Compassionate

Because, " thirteen multiplied by h is EQUAL TO ONE HUNDRED AND FOUR."

28. kellyp73

so do i have to find a number that is multiplied by 13 to make 104

29. Compassionate

Yes! :D You're getting it!

30. Compassionate

13 x h = 104 13 x 1 = 13 <-- this is not 104 13 x 2 = 26 <-- this is not 104.

31. kellyp73

ok so would it be 8

32. Compassionate

Yes! Because 13 x 8 = 104!!! :D

33. kellyp73

because 13 x 8 1s 104

34. Compassionate

Mhm. You see, it's easy! Try this one: 5 x y = 25

35. kellyp73

ok 5x5=25

36. Compassionate

Yes! So y is just any number that can be multiplied by 5 to equal 25.

37. kellyp73

ok here is one y+(-6)=-9

38. Compassionate

Do you know the first step?

39. kellyp73

what is the - signs for

40. kellyp73

is the y any number?

41. Compassionate

Okay. You need to know what pemdas is. Watch this video. https://www.khanacademy.org/math/arithmetic/multiplication-division/order_of_operations/v/introduction-to-order-of-operations

42. kellyp73

is this algebra? 5(b+8)

43. Compassionate

Anything with letters is. Sorry, but I have to go. Catch you on the flip side.

44. kellyp73

ok thank you so much for your help
