\( -3 + (-1.5) = \)

\( 1.5 + 3.5  =\)

\( \large\frac{1}{4} + \large\frac{1}{2} = \)

\( -1\frac{1}{2} + (-1\frac{1}{2}) = \)

\( 3 + (-5) = \)

\( (-1.5) + 4 = \)

Victor borrowed 21.50 dollars from his mother to go to the theater. A week later, he paid her 21.50 dollars back. How much does he still owe her?

Sandra used her debit card to buy lunch for 8.74 on Monday. On Tuesday, she deposited 8.74 back into her account. What is the overall increase or decrease in her bank account?

\( 2.75 + (-2) + (-5.25) = \)

\( -3 + (1\large\frac{1}{2}) + (2\large\frac{1}{2}) = \)

\(-12.4 + 9.2 + 1 =\)

\(-12 + 8 + 13 =\)

\(4.5 + (-12) + (-4.5) =\)

\( \large\frac{1}{4} + (-\large\frac{3}{4}) =\)

\( -4\frac{1}{2} + 2 =\)

\(-8 + (-1\frac{1}{8}) = \)

How can you use a number line to find the sum of -4 and 6?
