Write an expression that can be used to multiply 6 x 198 mentally? please answer thanks!

Answers

-6 x 2 + 6 x 200. Since you want to find out 6 multiplied by 198 the easiest way (for me) would be to round it and then substract 12 since 200-198 is equal to 2 and 6 x 2 is equal to 12

Assuming you meant 6 x 198... Do a mental sum for 6 x 200 (1200) then subtract 6

With 10 to the power to a negative number, it's easier.
Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.

From this, we get: $10^(-4)=\boxed{0.0001}$

10^4 = 10000 (four zeros at the end)
10^-4 = 0.0001 (four zeros at the front)
