Question

Add up the 4 numbers in base 5 then change the answer to base 10

Answer 1

2310+  (2×125+3×25+1×5=330₁₀+) [each number is converted into decimal using powers of 5]

3244+  (3×125+2×25+4×5+4=449₁₀+)

1333+  (1×125+3×25+3×5+3=218₁₀+)

4220    (4×125+2×25+2×5=560₁₀)

——-

     12₅

   200₅

 2000₅

20000₅

———   (1557₁₀)

22212₅=(((2×5+2)×5+2)×5+1)×5+2= [the answer is built up one digit at a time]

((12×5+2)×5+2)×5+1)×5+2=

(62×5+1)×5+2=

311×5+2=

1557₁₀

This shows two ways of arriving at the same solution.
