The easiest would be to multiply from left to right starting with 5 x 300 which
= 1500 then 5 x 0 =0 and 5 x 6 =30 then add them up 1500 + 0 + 30 =1530 multiplying from left to right removes the need to carry or borrow making it much easier to do mentally.
Mental math is basically just giving an estimate of what the value will be, for example: 5x306= 5x3 and add 2 zeros will give you 1500 and the actual answer is 1530 so its kind of like rounding off to the nearest.
1800
You can, if you wish.
70
move the decimal point to the right one space
13.48 - 6.1 in mental math = 7.380000000000001
how to do mental math useing propertys
mental math is doing the math in your head or in your mind but not in a calculator or pencil and paper
To find the product of 6 and 741 using mental math, you can break it down by distributing the multiplication. First, calculate 6 times 700, which is 4200, and then 6 times 41, which is 246. Finally, add these two results together: 4200 + 246 equals 4446. Thus, 6 times 741 is 4446.
Mental math is basically math in your head so for example 40x2=80 so I did that in my head
use mental math
50 what's "mental math" supposed to mean? if it just means you did it in your head, then there is no difference between mental and regular math, except that it is harder to check your work.
