Laura asks…
I am thinking about learning to knit or crochet. Which do you prefer and why?
The Expert answers:
I personally prefer crochet. It is simpler.
However, if you are looking for a wider variety of things you can make, then it is KNITTING, hands down.

Chris asks…
how do you add,subtract, multiply and divide negative and positive decimal numbers? would you like to ask?
The Expert answers:
Adding and Subtracting:
Lets have an example: 12.63+(-32.46)
first you have to line it up so that the decimal is in the same place
12.63
+-32.46
then you realize that adding a negative number is the same as subtracting a positive one
12.63
-32.46
Then you realize that this will end up a negative number, so you switch the numbers, with the intention of just making the number you come out with negative
32.46
-12.63
then you start at the end
6-3=3
4-6
you need to carry
14-6=8
remember you carried
1-2
you need to carry again
11-2=9
remember you carried
2-1=1
don’t forget to bring down the decimal
19.83
remember you switched the numbers, so make it negative
-19.83
Multiplication:
When multiplying, you are just going to forget about the decimals
example:
1.6*2.1
16
x 21
1*16=16
2*16=32
don’t forget that you need to add the place holders
16
+320
336
now you can put in the decimal
count the decimal numbers (all digits coming after the decimal point in both numbers)
there are 2, so count 2 places
its 3.36
remember, if one number is negative, make the answer negative
if both are either negative OR positive, make the answer positive
Division:
if the divisor has decimal numbers, multiply both the divisor and the dividend by 10 to the power of how many decimal numbers it has (10^2=100, and so on)
example: 15/2.5
multiply both by 10
150/25
its now a regular problem
if the dividend is a decimal, just bring it up
example 12.5/5
just do it ignoring the decimal
25
now bring up the decimal
2.5(I could show you better on paper)
I hope this helps
