Final answer:
To find (-4)-(-2) using all three methods of subtraction: Take-Away, Adding the opposite, and Missing Addend.
Step-by-step explanation:
To find (-4)-(-2) using all three methods of subtraction:
a) Take-Away: Subtract -2 from -4, which is the same as -4 - (-2). This can be rewritten as -4 + 2, and the answer is -2.
b) Adding the opposite: Replace -2 with its opposite, which is +2. Then, subtract -4 + 2, which is -2.
c) Missing Addend: We know that -4 + x = -2, where x is the missing addend. To find x, we can rewrite the equation as x = -2 - (-4). This can be simplified to x = -2 + 4, and the answer is x = 2.
