This works as follows: To multiply (say) 74 and 58 Write down 74 58 Double left and halve right 148 29 Again 296 14 Ignore remainders 592 7 1184 3 2368 1 Even numbers on the right hand side are evil and must be deleted along with their contaminated left hand partners, leaving: 148 29 592 7 1184 3 2368 1 Now add the left hand column and you get 4292, the correct answer!

How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
What do you do to find product of two numbers?
You multiply them. Addition = sum Subtraction = difference Multiplication = product Division = quotient
When you multiply 5 the ones digit in the product is one of these two numbers Name the numbers Explain how you know?

What is the product of 2 numbers?
A product is the answer to two multiplication problems. Example: 2*2=4 / product
What is the LCM of two co prime numbers?
Product of the two prime numbers is the LCM. For example 3, 7 have 21 as LCM
Does product and sum mean the same?
No - the product of numbers is the answer to a multiplication sum, while the sum of numbers is the answer to an addition sum.
How would you explain the LCM of the two numbers is their product?
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
the product of two even numbers is even and the product of odd numbers is odd explain with an example?
Any number, regardless of odd or even, if multiplied by an even number, is always even. Ex: 4x6 is 24 4x5 is 20 5x5 is 25
How can you determine whether the LCM of two numbers is the product of the numbers or is less than the product of the numbers explain?
If the two numbers have no common factors other than 1, the LCM will be their product. If there are other common factors, the LCM will be less.

Is the set of all negative numbers closed under the operation of multiplication Explain why or why not?
No. For a set to be closed with respect to an operation, the result of applying the operation to any elements of the set also must be in the set. The set of negative numbers is not closed under multiplication because, for example (-1)*(-2)=2. In that example, we multiplied two numbers that were in the set (negative numbers) and the product was not in the set (it is a positive number). On the other hand, the set of all negative numbers is closed under the operation of addition because the sum of any two negative numbers is a negatoive number.
Explain associative and commutative?
Commutative law: The order of the operands doesn't change the result. For example, 4 + 3 = 3 + 4. Associative: (1 + 2) + 3 = 1 + (2 + 3) - it doesn't matter which addition you do first. Both laws are valid for addition, and for multiplication (as these are usually defined, with numbers. However, special "multiplications" have been defined that are not associative, or not commutative - for example, the cross product of vectors, or multiplication of matrices are not commutative.

What is the product of two numbers?
The product of any two numbers is the answer to the multiplication sum. For example, in the sum 7 x 9 = 63, the number 63 is the product.
Explain how you can break apart arrays when you multiply by 3?
explain how you can break numbers apart to find the product of 7 X 13
What is the process of finding the product of two numbers called?
Multiplying. Yes, multiplication.
