To find the difference of \( 4.06 - 1.42 \):
-
Align the numbers:
4.06 - 1.42
-
Subtract as follows:
- Start from the rightmost digit: \( 6 - 2 = 4 \)
- Move to the next column: \( 0 - 4 \): Since you cannot subtract 4 from 0, you will need to borrow. Borrowing 1 from the 4 in the next column turns it into 3, and the 0 becomes 10. \( 10 - 4 = 6 \)
- Now, move to the last column: \( 3 - 1 = 2 \)
-
Putting it all together:
4.06 - 1.42 ------ 2.64
Thus, the answer is: \[ 4.06 - 1.42 = 2.64 \]
