Multiplication Algorithm Quiz

What is the first step in multiplying a two-digit number by a one-digit number without regrouping?

• Subtract the smaller number from the larger one

• Write the numbers on top of each other

• Multiply the tens place first

• Add a zero to the ones place

When multiplying two-digit numbers without regrouping, why do we add a zero in the ones place of the second number?

• To simplify addition

• To avoid carrying over

• To keep the value of the tens digit

• To make the calculation easier

Why is it important to add a zero beneath the ones place when starting a second number in multiplication?

• To avoid errors

• To simplify the addition

• To maintain the place value

• To make the number larger

What is the result of multiplying 42 by 14 using the algorithm without regrouping?

• 588

• 672

• 128

• 210

In the context of multiplication with regrouping, what does it mean to 'carry' a number?

• To divide the number by ten

• To subtract from the total

• To move a digit to the next column

• To add a zero to the result

In multiplication with regrouping, what should you do after multiplying the ones place?

• Add the results together

• Multiply the tens place

• Carry over any extra value

• Subtract the smaller number

What is the result of multiplying 74 by 3 with regrouping?

• 444

• 296

• 148

• 222

What is the purpose of crossing off the carried number in multiplication with regrouping?

• To simplify the process

• To indicate a mistake

• To mark the end of a calculation

• To ensure it is not added again

When multiplying 85 by 6, what is the result after adding the carried number?

• 60

• 30
