Calculate 1×2×3: Multiplying Three Sequential Numbers

To solve this problem, we perform the following steps:

• Step 1: Begin with the first multiplication, $1 \times 2$.
• Step 2: Multiply the result from Step 1 by the third number, $3$.

Now, let's execute these steps:

Step 1: Compute $1 \times 2 = 2$.

Step 2: Continue by multiplying the result from Step 1 by $3$, which is $2 \times 3 = 6$.

Thus, the result of multiplying $1 \times 2 \times 3$ is $6$.
