HELLO. I´M FROM BRAZIL AND NEED HELP WITH NUMBERS IN ENGLISH. I´D LIKE TO KNOW:
1) IF COMMAS ARE NECESSARY WHEN WRITING LARGE NUMBERS. FOR EXAMPLE:
FIVE THOUSAND SEVEN HUNDRED AND THIRTY-THREE OR FIVE THOUSAND, SEVEN HUNDRED AND THIRTY-THREE?
2) IF THE "AND" IS NECESSARY OR I CAN JUST SAY FIVE THOUSAND SEVEN HUNDRED THIRTY-THREE;
3) IF IT´S CORRECT TO SAY "A THOUSAND A HUNDRED TWO" (1102);
4) IF THERE´S A RULE FORE SUBSTITUTING "ONE" BY THE ARTICLE "A", LIKE THE EXAMPLE BEFORE.


THANK YOU VERY MUCH!!!!
