Can I enter negative numbers and decimals?

Question

In the previous example, the numeric entry field automatically formatted your entry after you entered a value and exited the field. In some cases, however, you’ll need to enter a minus sign to represent a negative number, or a decimal to represent a noninteger.
Complete the following table to see how decimals and negative numbers work.
X

Y

X + Y
2,721.9 3,443.8
2,200.0 -2,700.0

Answer 1

Certainly! Let's complete the table step by step by calculating the values for \(Y\) and \(X + Y\).

1. For \(X = 2,721.9\) and \(Y = 3,443.8\): \[ X + Y = 2,721.9 + 3,443.8 = 6,165.7 \]

2. For \(X = 2,200.0\) and \(Y = -2,700.0\): \[ X + Y = 2,200.0 + (-2,700.0) = 2,200.0 - 2,700.0 = -500.0 \]

Now we can fill in the completed table:

| X | Y | X + Y | |-----------|-------------|------------| | 2,721.9 | 3,443.8 | 6,165.7 | | 2,200.0 | -2,700.0 | -500.0 |
