Hey There!
Steps to solve (Steps will be in numerical order)
1. Set up the equation 13.480-8.2633.
2. Since you have to subtract from left to right, First subtract 10-3=7, you get the 10 because you have to regroup, regrouping means taking away from tens . Since you regrouped 0, you have to take away one number from 8, so now you have to solve 7-6=1, next is 4-2=2, you have to solve 3-8 now, since you cant subtract 3-8, you regroup and change 3 to 13, now you are solving 13-8 which equals to 5, next since you regrouped you subtract 1-1 which equals zero.
In conclusion, 13.480-8.263=5.217
Hope This Helped :)
