Answer:
10220
Explanation:
You start by adding each pair of numbers from the right.
The result must satisfy the following conditions
1. If the result is less than 3, you write down the figure
2. Else if the result is greater than or equal to 3 then
2.1 You divide that result by the base (3).
2.2 You write than the quotient
2.3 then add the remainder to the next addition
2.3 if there's no other number to add, you write down the quotient in front of the remainder
1 1 1 1
+ 2 1 0 2
Step 1: Starting from the right, we add 1 and 2.
i.e. 1 + 2 = 3
Going by the condition(2) stated above, we have to divide the result (3) by the base (3)
3/3 = 1 remainder 0
The quotient is 1
Remainder is 0
Note: You write down the remainder (0), then you add the quotient(1) to the next addition of numbers.
1 1 1 1
+ 2 1 0 2
------------------------
0
Step 2: You then move to
1 + 0 = 1
The remainder from the previous addition must be added to this
So, we have 1(remainder) + 1 = 2
Going by the condition (1) stated above, you write down the resulting figure
1 1 1 1
+ 2 1 0 2
------------------------
2 0
Step 3: You then move to 1 + 1
1+1 = 2
This also satisfy condition 1.
You write down the resulting figure.
1 1 1 1
+ 2 1 0 2
------------------------
2 2 0
Step 4: You then move to 1 + 2
1 + 2 = 3
Going by the condition(2) stated above, we have to divide the result (3) by the base (3)
3/3 = 1 remainder 0
The quotient is 1
Remainder is 0
You write down the remainder (0)
1 1 1 1
+ 2 1 0 2
------------------------
2 2 2 0
Since there's no other number to add, you then write then quotient (1) in front of the remainder
1 1 1 1
+ 2 1 0 2
------------------------
1 2 2 2 0
Since there's nothing more to add, you then write down the quotient in front of the remainder
