What is 9 times 52 using mental math property
arsen [322]
Everyone works differently in mental meth.

To calculate 9*52, we note that 9=10-1, so mentally calculate
9(52)
=(10-1)(52)
=520-52   [ subtract 20 from each number]
=(520-20)-(52-20)  
=500-32
=468.

Alternatively,
9*52=9*50+9*2=450+18=468

If  you're good with multiplication and division,
9*52=3*3(52)=3*156=450+18=468

What is a coefficient ?
Ahat [919]
A coefficient is a number that is attached to a term.

For example:

3x² - 5x + 6 = 0                 

The coefficient of x² is 3.

The coefficient of x = -5. 

Hope this explains it.
