Solve for Missing Values: Complete ?:?+23×1=23 Equation

Let's solve the problem step by step:

The expression given is $?:? + 23 \times 1 = 23$. We will analyze the parts:

• First, simplify $23 \times 1$, which equals $23$.
• Therefore, the problem reduces to $?:? + 23 = 23$.
• For the equation to hold, the addition with 23 must be zero: $?:?$ must simplify to zero.
• The only way for $?:?$ to be zero is if it is $0:2$, because dividing zero by any non-zero number results in zero.

Thus, the division $0:2$ gives us $0$, satisfying $0 + 23 = 23$.

Therefore, the missing values are $0, 2$.
