I don’t know if there is some trick or setting on the copier, but this book I teach from has worksheets with answers on the them, but they’re in blue. I tried lightening the darkness, but that didn’t work. Any ideas?
your a teacher!!!?? you should be ashamed..putting us through all this misery…let the students see the answers! you meanie..
Sorry to be rude sir..
We have tons of homework every night. I do not mind passing it down. That is what it is all about. However, I truly do not remember how I learned to add and subtract. Funny, I know. I do remember MEMORIZING my Multiplication and Division Tables. So… I showed him with pennies, and then we did it with fingers, and then we wrote it down….then we said it over and over and over 5 times each….??????? Thx. 
The most important things to remember are that kids need to be taught in a variety of ways and they need repetition. If your child does not have a concept of what a 5 actually is… then adding 5 plus 5 means nothing to him. Keep using objects, fingers, ruler, hundred chart, number line etc. You can go online for printable games and online games. You can visit your local teacher supply store for flashcards and board games. (My students also like to use addition Wrap Ups). Teach him to always start with the biggest number and add up. Example: 8+2 "Which number is the biggest? Find the 8 on your ruler and count up 2".
It may help for him to know the cumulative property, the concept that 8+2 has the same answer as 2+8. When doing an addition worksheet, I have kids do the first problem, then go on a search to find other problems they can "cheat" on. It’s great that you are willing to take the time to help him with his homework; all kids should be so lucky.
I’m in high school going on to college and i still don’t know how to divide fractions. Can someone show me step by step an example of how to. It’s not that i’m slow or anything, but my elementary school that i went to never went over fractions.
Without any explanation of theory the best way I find to do it is to flip one of the fractions and multiply them together. For example:
(2/3) / (4/9)
will then be written as…
(2/3) / (9/4)
You then multiply both the numerators and both the denominators
2*9=18
3*4=12
and you get the answer:
18/12
which can simplify down to
3/2 or 1 and 1/2
hope i helped
Ps it doesn’t matter which fraction you flip as long as its only one that you do flip.
I have an old non digital thermostat and when i take the cover off, there is a dial with decimals on it.
.15 - 1.2
I’m pretty sure it represents how long the heater/aircon will stay on and then shut off, but can someone explain it to me?
Called a heat anticipator. The numbers are the amp draw on the low voltage when the heat is energized. The higher it is set the longer the heat cycle will be.
If set too high it may overshoot the temperature setting.
Too low and it will cycle the heat off before it reaches temp.
Solve the system of equations using the Addition method.
2a + 3b = -1
3a + 5b = -2
I thought you had to be able to eliminate a variable in the first step meaning the +5b would have to be -3b, otherwise i have no clue how to do this, can anyone help me? If you give an answer please explain.
You can MAKE a variable cancel by multiplying each equation by the coefficient of the variable you want to eliminate. For example:
2a + 3b = -1
3a + 5b = -2
Say we wnat to eliminate the "a" term. The first equation has "2a" and the second one has "3a." Multiply the first equation by 3 and the second equation by 2.
6a + 9b = -3
6a + 10b = -4
Now subtract the second equation from the first one.
. .6a + 9b = -3
- .6a + 10b = -4
==============
-b = 1 . . . . .so b = -1; to find a, put b = -1 into either of the two original equations.
Using eq. 1, 2a + 3(-1) = -1
2a - 3 = -1
2a = 2
a = 1
Hi,
I am using BAII Plus calculator.
I just want to know how to change decimal points to fractions . For example the calculator displays 0.571428571 instead of 4/7. I need to know this because sometimes the answer for the exam question only provides fraction numbers instead of decimal numbers. How do I need to know if the decimal numbers is so big that I dont know how to change it to fraction numbers?

this is a link to the manual for that calculator; i couldn’t find anything in there that described your dilemma. But doublecheck behind me. you might just have to borrow someone else’s calculator that does have a F to D key on it. Your kind of calculator is not one I find with my high school students.
I would like to know the insights of various people, not just scientists, as to what they think happened during the first fractions of a second after the big bang. I’d be thrilled to know every person’s view regarding this. Who knows, maybe a few of you could somehow outsmart those CERN scientists who are now gearing up to test the Large hadron Collider!
In the first fraction of a second after the big bang, there was a very bright light, then the expansion outward of the super hot gases.
So there you have the first second of the big bang.
I mean to help a child learn english themselves by doing the worksheets as they have to learn themselves.
Try this site, I use it for Maths for my son but it has English

I need help with my math homework. I need to make a chart that has the similarities and differences between addition and subtraction. Here’s what I have so far:
Addition:
Adding a number to another number
Answer is the sum
Subtraction:
Taking away a number from another number
Answer is the difference
Yes, I do understand they are not really related, but I need SOMETHING to write for similarities. ANYTHYNG!!!
Addition combines two numbers or values. Subtraction tells you how far apart they are on the number line. The two are really quite unrelated.
A fraction will be one-half if one is added to the numerator and subtracted from the denominator.
Numerator—n:
(n + 1)/(3n – 1) = 1/2
3n – 1 = 2(n + 1)
3n – 1 = 2n + 2
n = 3
Denominator:
= 3(3)
= 9
Answer: 3/9 is the fraction.
