Math Problem Statement

I need to show my work

Multiply 73 x 45 and show your work.

Solution

Let's solve 73×4573 \times 45 step-by-step, showing the work.

Step-by-step multiplication:

  1. Break the multiplication into parts using the distributive property: 73×45=73×(40+5)=(73×40)+(73×5)73 \times 45 = 73 \times (40 + 5) = (73 \times 40) + (73 \times 5)

  2. Multiply each part:

    • First, multiply 73×4073 \times 40: 73×40=292073 \times 40 = 2920

    • Now, multiply 73×573 \times 5: 73×5=36573 \times 5 = 365

  3. Add the two products together: 2920+365=32852920 + 365 = 3285

Final Answer:

73×45=328573 \times 45 = 3285
