When Charlee's calculator shows 1.78E12, it means that the number is in scientific notation. The "E" stands for "exponent," which is another way of saying "times ten to the power of."
So, 1.78E12 can be interpreted as:
1.78 × 10¹²
This means that you take 1.78 and multiply it by 10 raised to the 12th power.
To understand this better, 10^12 (or 10 to the power of 12) equals 1,000,000,000,000, which is 1 followed by 12 zeros.
Now, if you multiply 1.78 by 1,000,000,000,000:
1.78 × 1,000,000,000,000 = 1,780,000,000,000
So, 1.78E12 really means that Charlee's calculator is showing the number 1,780,000,000,000, which is a very large number!
