Question

40 how find the sum
-0.25 - 1.5 = -0.25 + (-1.5)
= \boxed{}

Explanation:

Step1: Recall the rule of subtraction

Subtracting a number is the same as adding its opposite, so \(-0.25 - 1.5=-0.25+(-1.5)\).

Step2: Add the two negative numbers

To add two negative numbers, we add their absolute values and keep the negative sign. The absolute value of \(-0.25\) is \(0.25\) and the absolute value of \(-1.5\) is \(1.5\). So we calculate \(0.25 + 1.5 = 1.75\), and then apply the negative sign, getting \(-1.75\).

Answer:

\(-1.75\)
