Use algebra tiles to find the difference. Let one white tile equal +1 and one black tile equal -1.
12-(-11)
1
23
18
23
To find the difference between 12 and -11 using algebra tiles, we can represent 12 with 12 white tiles (+1) and represent -11 with 11 black tiles (-1). We then subtract the number of black tiles from the number of white tiles to find the difference.
12 white tiles (+1) - 11 black tiles (-1) = 1 white tile (+1)
Therefore, the difference between 12 and -11 is 1.
To find the difference 12 - (-11) using algebra tiles, we can represent 12 with 12 white tiles (+1 each) and represent -11 with 11 black tiles (-1 each).
Now we will subtract -11 from 12 by removing 11 black tiles from the arrangement of 12 white tiles.
Starting with 12 white tiles, remove 11 black tiles:
12 - (-11) = 12 + 11 = 23
So, the difference 12 - (-11) is equal to 23.
To use algebra tiles to find the difference between 12 and -(-11), you can start by representing each number with the corresponding tiles.
For 12, you will use 12 white tiles (+1 each) and for -(-11), you will use 11 black tiles (-1 each).
Now, to subtract -(-11), you need to change the double negative into a positive. It becomes +11.
Next, you can physically match the tiles to simplify the subtraction process.
Place 12 white tiles on the table, and then remove 11 black tiles.
Count the total number of tiles left, which will give you the difference between 12 and -(-11).
In this case, you should have 1 white tile remaining after removing 11 black tiles.
Therefore, the difference between 12 and -(-11) is 1.
