dont know about associative property but this one is easy in your head. 4x25=100x27=2700
Are compatible numbers difficult to compute mentally?
No.
What can you use to estimate quotients when they are easy to compute mentally?
Your brain, of course.
Are numbers that are easy to compute mentally?
It depends on your computational skills.
What are the patterns and properties to compute mentally for 120 times 30?
The patterns and properties to compute mentally 120 times 30 is the numbers 12 and 3 plus the two 0. Multiply 12 by 3 (36) and add the two 0 (3600).

How do you compute square roots mentally?
There are many ways to do it. Have a look at the Wikipedia article (check the link).
How do you compute 4x25x27 mentally?
Break it up into two separate problems. First 4X25=100, which is easy enough. Then 27X100=2700.
Numbers that are easy to compute mentally?
Numbers like 10, 25, 50, and 100 are easy to compute mentally because they have simple multiples or divisions that are easy to work with. For example, doubling 25 is 50, or dividing 100 by 10 gives you 10. These numbers are often used as benchmarks in mental math calculations.
What term describes Numbers that are easy to compute mentally?
The term that describes numbers that are easy to compute mentally is "round numbers." Round numbers are whole numbers that end in zero or five, making them simpler to work with in mental calculations. These numbers are often used in estimation and quick arithmetic tasks due to their ease of manipulation.
Are numbers easy to compute mentally?
No, but if you practice you can learn to do it and it gets easier. Start of by learning (by rote) your times tables and when adding up do so in 10s.
