PS4MA Multiplication Medium

Multiplication is a mathematical operation that combines two numbers, called factors, to find their product or total.

A one-digit multiplier is a number with only one digit, used in multiplication.

A two-digit multiplier is a number with two digits, used in multiplication.

The process of expanding a number into its place values (ones, tens, hundreds, etc.)

The process of carrying over extra digits from one place value to the next during multiplication.

Multiplying two-digit numbers by a one-digit multiplier involves multiplying each digit of the two-digit number by the one-digit multiplier, then adding the results.

Multiplying two-digit numbers by a two-digit multiplier involves multiplying each digit of the first number by each digit of the second number, then adding the results.

A vertical alignment of numbers by place values, used for multiplication.

The act of combining results from individual multiplications during a complex multiplication problem.

The concept of multiplication where multiplying by 10, 100, etc., simply moves the decimal point to the right.

A method of multiplying numbers by breaking down the process into smaller steps, focusing on individual digits and place values. It involves multiplying each digit of the multiplicand by each digit of the multiplier, then adding the results.

A visual method of multiplication where numbers are placed in boxes, and the multiplication of individual digits is performed to fill the boxes. The results are then added diagonally to get the final product.

The process of multiplying a multi-digit number by a single-digit number, breaking it down into individual digits and place values. Each digit is multiplied separately and then added together.

The method of multiplying numbers by writing them in a horizontal format and then multiplying each digit of the multiplier by each digit of the multiplicand, starting from the ones place and moving to the left.

The concept of carrying over a value from one place value to the next place value when the result of a multiplication exceeds the capacity of that place value. For example, if 7 x 8 = 56, the 5 tens are carried over to the tens place.

The value a digit holds in a number based on its position. For example, in the number 123, the digit 1 represents the hundreds place value.

The number being multiplied in a multiplication problem.

The number that indicates how many times the multiplicand is to be added to itself.

The result obtained after performing a multiplication operation. It is the product of the multiplicand and the multiplier.

The process of multiplying a multi-digit number by a two-digit number, breaking it down into steps and focusing on individual digits and place values.

The process of multiplying a number by ten or a power of ten (like 100, 1000) simply shifts the decimal point to the right by the number of zeros in the multiplier.

When multiplying numbers with multiple digits (like 123 x 45), the process involves multiplying each digit of the first number by each digit of the second number, then adding the results.

In multi-digit multiplication, we often need to carry digits over to the next place value when the product of two digits exceeds 9.

A word problem involving multiplication asks you to find the total amount when combining equal groups or quantities.

When multiplying two-digit numbers, align the numbers vertically by place value (ones, tens). This helps make the multiplication process organized and easier to manage.
