101010₂ = 0*2⁰ + 1*2¹ + 0*2² + 1*2³ + 0*2⁴ + 1*2⁵ = 42₁₀
42₁₀ = 2*10⁰ + 4*10¹ = 42₁₀
1037₉ = 7*9⁰ + 3*9¹ + 0*9² + 1*9³ = 763₁₀
763₁₀ = 3*10⁰ + 6*10¹ + 7*10² = 763₁₀
AD₁₆ = D*16⁰ + A*16¹ = 173₁₀
173₁₀ = 3*10⁰ + 7*10¹ + 1*10² = 173₁₀

169₁₀ = 1*2⁰ + 0*2¹ + 0*2² + 1*2³ + 0*2⁴ + 1*2⁵ + 0*2⁶ + 1*2⁷ = 10101001₂
169₁₀ = 1*8⁰ + 5*8¹ + 2*8² = 251₈
169₁₀ = 9*16⁰ + 10*16¹ = A9₁₆

11001₂ = 1*2⁰ + 0*2¹ + 0*2² + 1*2³ + 1*2⁴ = 25₁₀
101₂ = 1*2⁰ + 0*2¹ + 1*2² = 5₁₀
30₁₀ = 0*2⁰ + 1*2¹ + 1*2² + 1*2³ + 1*2⁴ = 11110₂
125₁₀ = 1*2⁰ + 0*2¹ + 1*2² + 1*2³ + 1*2⁴ + 1*2⁵ + 1*2⁶ = 1111101₂
11001₂ + 101₂ = 11110₂
11001₂ * 101₂ = 1111101₂
