Answer: the difference between two numbers can be obtained by subtracting the smaller number from the bigger number.
• Here, - 0.4 is the smaller number, and 44.4 is the larger number.
• Therefore, the difference between the two is 44.4 - (- 0.4).
• Now, in mathematics, - and - makes a +.
This implies that, 44.4 - (- 0.4) = 44.4 + 0.4 = 44.8
∴ The required difference is 44.8.
