How do you find the product of compatible numbers?
Assuming that we know the multiplication table, all pairs in the multiplication table, including any variation with added 0s on the end, are compatible numbers. Find the product or quotient of the following pairs of compatible numbers. 40 × 3000 is the same as 4 × 3, with 4 added 0s.
What are some examples of compatible numbers?
Some examples of compatible numbers when doing multiplication are 200 and 40, 1100 and 40, 25 and 4. 1100 and 40 are compatible because we can quickly do this multiplication by multiplying 11 and 4 to get 44 and add three zeros at the end to get 44000.

Why are compatible numbers used?
Compatible numbers. Compatible numbers are numbers that seem to "go together" because they are easy to compute mentally. For various reasons, it is easier to compute addition, subtraction, multiplication, and division problems mentally using compatible numbers than numbers that are not compatible. As such, compatible numbers are commonly used ...
What is compatible with multiplication?
Compatible numbers for multiplication and division are very similar. Like with addition and subtraction, numbers that end in one or more 0s are typically compatible. For multiplication, 0 multiplied by anything is 0, so zeros on the end of multiplication problems can be removed. For multiplication, any zeros ...
What is the rule for a number that ends in 0?
One general rule that applies to all the basic arithmetic operations is that numbers that end in 0 (or multiple 0s) are compatible numbers , since in most cases they are easier to work with.
Why are numbers that end in 0 compatible?
Like in addition, numbers that end in 0 are compatible numbers because we can largely ignore the 0s, perform the subtraction, then attach the appropriate number of 0s after. Numbers that end with the same final digit are therefore compatible, since subtracting any number by itself results in 0.
Do you have to break up numbers to recognize them?
It is not actually necessary to break the numbers up if you recognize them, but when doing the mental math, recognizing these numbers is as if you are doing so. This is why such numbers are referred to as compatible numbers, since, with some practice, they become easily recognizable to us.
