-3 - (-9)
Draw two arrows to show -3 - (-9)
To show -3 - (-9), we can draw two arrows.
First, let's draw an arrow pointing to the left with a length of 3 units, representing -3.
<--
Next, let's draw another arrow starting at the end of the first arrow, pointing to the left with a length of 9 units, representing -(-9).
<-- <---------
Finally, let's find the difference between the two arrows by subtracting the second arrow from the first arrow:
<-------------------
<-- <---------
The resulting arrow is pointing to the right with a length of 6 units. Thus, -3 - (-9) = 6.
To visualize -3 - (-9), here's how you can draw two arrows:
1. Start with an arrow pointing to the left. Label it with -3.
-3 ←
2. Next, draw a second arrow starting from the tail of the first arrow and pointing to the right. Label it with -(-9) or simply 9.
-3 ← 9
This represents the subtraction -3 - (-9). The two arrows together indicate that we are subtracting -(-9), which is equivalent to adding 9.
To solve the expression -3 - (-9), we can follow these steps:
Step 1: Simplify the expression within the parentheses.
-3 - (-9) becomes -3 + 9.
Step 2: Add or subtract the numbers.
-3 + 9 equals 6.
To represent this visually with arrows, we can use the number line. Here's how you can draw the arrows:
1. Draw a horizontal line representing the number line.
0 --------->
2. Mark the numbers -3 and -9 on the number line.
-9 -3 0 --------->
3. Draw an arrow starting from -3 and pointing towards the right (+) for the first subtraction: -3 - (-9).
-9 <--- -3 0 --------->
4. Then, draw another arrow starting from -3 and pointing towards the right (+) to represent the addition of 9.
-9 -3 ---> 6 0 --------->
The final position of the arrow on the number line, pointing to the number 6, indicates the result of -3 - (-9), which is 6.
