someone can help me today i received my arduino uno r3 kit but i have problem with resistors . i have one package in blue color resistor with brown ,black, black, red ,red and other resistors they have brown,black,orange,gold . i uploded also pics if someone can help me thanks very much

The first two colors are regular digits, the 3rd is the multiplier (or the number of zeros) and the 4th is the tolerance. (Gold is 5%).
brown,black,orange,gold
That's a 10K Ohm resistor -
Brown =1
Black =1
Orange = 3 more zeros
=10,000 Ohms
brown ,black, black, red ,red
I think you're reading that one backwards. It's a 1% resistor (brown tolerance band) so it's got an extra color band.
Red = 2
Red = 2
Black = 0
Black = 0 (no additional zeros)
220 Ohms.
It's also a really good idea to get a multimeter so you can measure the resistance and confirm you're reading it right...
So when i read a resistor always i have to start from brown color side ?
This project could help you learn.

Sometimes it is not obvious which way round to read the stripes - you always have the
option of measuring with a multimeter (also handy when the resistor body is blue and
the orange and brown colours are hard to distinquish against a coloured background)
