Part of the problem might be that you're unfamiliar with the terminology- which would be true of a lot of people who aren't currently taking math - it's amazing what'll come back to you when you go through a math book.
The multipliers are the numbers you are multiplying together to find the answer (which is called a product when it's found by multiplying). So 63 and 65 are your multipliers. 4095 is your product. 4095 is a multiple of 5 - you know that because it ends in 5. When someone says something is a multiple of 5 that means that the number 5 can be divided into it evenly with no remainder. Just like 100 is a multiple of 10 because ten can be divided into 100 evenly.
Any number that ends in 5 or 0 is a multiple of 5 (if you count by fives you will say all the multiples of 5).
When a number ends in 5 - we know for sure that another number that ends in 5 has to be one of the multipliers (as long as we're talking about whole numbers). So in this problem, that tells you that one of the multipliers is either 55 or 65 because those are the only two whole numbers between 50 and 70 that end in 5 (or that have a 5 in the ones place).
At this point I rounded off 4095 to 4000 in my head and I said to myself - even if I multiply 55 by 70 (even though I knew that wouldn't give me 4095 because I'd have a 0 in the ones place instead of a 5) that would only get me 3850 - less than 4000- so the only other choice of a multiplier that ends in 5 is 65 and once you have that it's very simple and fast to divide the product they gave you (4095) by 65 and get the other multiplier (63).
Quote:It used to reduce me to tears at school cos I just could not get my head round certain things.
I felt the same way about science after biology. I got biology - but I just couldn't get chemistry and I struggled through that and then gave up on science- concentrating on math and english -which I liked. That was fine on one level, but sad on another because I really did think there was something wrong with my brain and I couldn't learn science.
But then when I was an adult and teaching I used to sit in the highschool science classes and I was amazed at how much better I was at comprehending the text, the teacher, etc.
Maybe because the pressure was off - maybe my concentration was better and more focused on the information instead of all the other stuff I found to think about when I was actually in highschool - I don't know...I know it wasn't the information that had changed so it had to be something about me.
Quote:God knows how I will help her with the maths homework when she's at high school.
Do whatever she's doing with her now as she's doing it. I don't mean do it FOR her, but have your own paper and do it as she's doing it. Having her explain to you whatever she learned in class that day will reinforce the lesson in her mind which can only help her and you sitting there with her will force you to learn step by step (which is how you have to learn math) what either you didn't ever learn in the first place or have forgotten.
This is a good spot to start. Once she gets into fractions, decimals, percents, etc...and onto geometry and algebra - if you haven't got the foundation down- numeration, multiples, factoring, etc.- it'll be much harder to just jump in and automatically recollect all the stuff you've forgotten.
Good luck!
