440000 because the decimal is positive you move the decimal place five places to the right.
You would first subtract 2 from both sides. Then add n to both sides. Then you would divide 16 by 2 and you would get n=8
For part 2, you would use 3 thousands, as that is the biggest amount possible so far. The, you would use 1 ten [instead of 16 ones] and then 6 ones bacuse that is the smallest amount.
You’re answer should be m= -2
The answer would be 9 you would add the 13 and 7 then have 20-5t=-25 then subtract 20 from 25 then you would have -5=-45 which is 9
