Questions and Answers
Explain why multiplying any number by 10 is equivalent to adding a zero to the end of that number. Provide a concrete example to illustrate your explanation.
Multiplying by 10 shifts each digit one place to the left, effectively adding a zero to the rightmost position. For example, 12 multiplied by 10 becomes 120. The digit 1 shifts from the tens place to the hundreds place, while the digit 2 shifts from the ones place to the tens place, leaving a zero in the ones place.
Describe a pattern you observe in the diagonal of the multiplication table starting at the top left corner and moving to the bottom right corner. How does this pattern relate to the properties of multiplication?
The diagonal consists of all perfect squares, each number being the square of the number in the corresponding row and column. This pattern reflects the property of multiplication that squaring a number is equivalent to multiplying it by itself.
Without using the multiplication table, explain how to calculate 6 x 7 using the distributive property of multiplication. Show your steps.
We can break down 6 x 7 as (5 + 1) x 7, then apply the distributive property: (5 x 7) + (1 x 7) = 35 + 7 = 42.
Explain why multiplying a number by 5 is equivalent to multiplying by 10 and then dividing by 2. Give a specific example to illustrate your reasoning.
