To solve the expression -6 + 14 using a number line, we start at -6 on the number line and then move 14 units to the right.
Starting at -6, we can count to the right by adding 1 each time until we reach 14.
-6 + 1 = -5
-5 + 1 = -4
-4 + 1 = -3
-3 + 1 = -2
-2 + 1 = -1
-1 + 1 = 0
0 + 1 = 1
1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
4 + 1 = 5
5 + 1 = 6
6 + 1 = 7
7 + 1 = 8
8 + 1 = 9
9 + 1 = 10
10 + 1 = 11
11 + 1 = 12
12 + 1 = 13
13 + 1 = 14
Therefore, starting at -6 and moving 14 units to the right on the number line, we reach the answer of 8.
To solve the expression -5 - 7 using a number line, we start at -5 on the number line and then move 7 units to the left.
Starting at -5, we can count to the left by subtracting 1 each time until we reach 7.
-5 - 1 = -6
-6 - 1 = -7
-7 - 1 = -8
-8 - 1 = -9
-9 - 1 = -10
-10 - 1 = -11
-11 - 1 = -12
Therefore, starting at -5 and moving 7 units to the left on the number line, we reach the answer of -12.
I hope this helps! :)
