STEP: 1 足し算
puts 1_231 + 5_178
STEP: 2 引き算・掛け算
a, b = gets.split.map(&:to_i)
puts "#{a - b} #{a * b}"
STEP: 3 割り算
a = 437_326
b = 9_085
puts "#{a / b} #{a % b}"
STEP: 4 掛け算 2
a, b, c = gets.split.map(&:to_i)
puts "#{a * a} #{b * b + c * c}"
STEP: 5 累乗
a, b, c = 202, 134, 107
puts ((a + b) * c) ** 2
FINAL問題 累乗 2
a, b, c, d = gets.split.map(&:to_i)
puts (((a + b) * c) ** 2) % d
STEP: 1 代入演算 1
n = 0
n += 3_286
n *= 4_736
n %= 12_312
puts n
STEP: 2 代入演算 2
a, b, c = gets.split.map(&:to_i)
n = 0
n += a
n *= b
n %= c
puts n
STEP: 3 代入演算 3
n = 10_000
n /= 361
n %= 28
puts n
FINAL問題 代入演算 4
a, b = gets.split.map(&:to_i)
n = 10_000
n /= a
n %= b
puts n
