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=
