In language usage (not mathematical meaning),"twice as many A as B" means A is two times more thanB — or as you put it, A = 2B. It's the same as saying it inthese alternative ways:— “A is twice asmany/much as B.” — ( In your question detailsalready) “Twice as many/much A asB.”
Correspondingly, what does twice as mean in math?
Twice a quantity usually indicates to take two ofthe things in question; usually this indicates to multiply by 2.Thus "twice a number x" can be written symbolicallyas 2x. If this is part of a problem, say twice anumber x is 6, then we can rewrite algebraically as 2x=6;dividing both sides by 2 yields x=3.
Besides, what is twice as much as 1?
The answer is simple: it isn't - "two times more" wouldmake that 1-dollar item cost 3 dollars (1 + 2 *1 = 3)! "X times more" means addition on top of what youalready have! "One time more" means the same as "one hundredpercent addition", or "twice as much", or "double theamount".
Greater Than. more Bigger. The symbol >means greater than (the symbol < means lessthan). Example: 5 > 3 shows that 5 is greater than3.
