i don't want the arswer just how to get them 1. 4 1/3 + 3 1/2 2. 2.34 + .0036 3. (-19) -21 4. x3 + ab4-z

Answer 1

1. to add the fractions, make them have the same denominator (bottom number). you can muliply the top and bottom number of any fraction by the same number without changing it's overall value. mulitply the 1/3 by 2/2, so you get 2/6. Multipy the 1/2 by 3/3 so you get 3/6. Now that you have the denominators the same (both have a 6 on the bottom), you can add the fractions. 2/6 plus 3/6 is 5/6. Add the whole numbers and you get 7 and 5/6

2. line the numbers up by where the decimal point is and add down.
2.34
+.0036
2.3436

3. If this is neg. 19 times neg. 21, you just multiply the 2 numbers. the 2 negs make a positive.

4. I have no idea!

Answer 2

well, do what it says. add subtract multiply divide etc.
Next time pay attention in class. Or maybe look in your algebra book. You will have a real hard time when you get into high math. Just decide that you are going to learn this stuff, or else you will contribute to this country being feeble in the future, and I will be pissed at you for not doing what your supposed to, and it ended up screwing my childover. If you dont learn this stuff, then we wont be able to say to our children that this is the greatest country in the world anymore.

Answer 3

for #1, make the fractions have the lowest possible common denomanator, which in this case is 1/6. for #2 think of it this way: 2.3400 + 0.0036 for #3, add them as if they were positive numbers, then put the negative sign in front and #4, i have no clue sorry

Answer 4

This is not a real math problem. It is a bunch of random numbers and symbols. I took pre-calculus and this appears to me to be nothing but a poor joke.

your not going to get an answer because there is no question.

But that's what you were looking for right?
