Subtract 90 - 46.
replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.
As many times as you want. If what you mean is, how many times can you subtract 2 from 46 before you hit zero (that is, "how many times does two go into 46") the answer is 23.
You can only subtract 5 from 25 once because after the first time it is no longer 25 :)
When you add, your answer is the sum.When you subtract, your answer is the difference.
