When you multiply a number by 1, the product is that number.
Junior says the product of 25 x 10 is 250. How can you use patterns to check Junior's answer?
Any multiple of 10 will always have a 0 in the ones place. Write the factor Junior is multiplying by ten (25), then write a 0 to the right of the factor to find the product (250).
