The display reading of 1.78E12 indicates that the calculator is using scientific notation to represent a very large number. In scientific notation, "E" stands for "exponent" and is shorthand for "times ten raised to the power of."
In this case, 1.78E12 means:
\[ 1.78 \times 10^{12} \]
To convert this to standard notation, you can multiply 1.78 by 10 raised to the power of 12. This involves moving the decimal point in 1.78 twelve places to the right.
So, in standard notation, 1.78E12 is:
\[ 1,780,000,000,000 \]
This represents the number 1 trillion 780 billion. Essentially, Charlee's calculator is showing that the product of the two large numbers is 1.78 trillion.
