To determine which statement is NOT true, let's evaluate each equation provided:
-
11 = 1111: This is NOT true. The number 11 is not equal to 1111.
-
18 - 711 + 5 = 15: Let’s calculate it.
- \( 18 - 711 + 5 = 18 - 711 + 5 = -693 \)
- This does not equal 15 (which makes this statement false as well).
-
1111 + 3 = 6 + 8: Let's check this.
- \( 6 + 8 = 14 \)
- \( 1111 + 3 = 1114 \)
- Since 1114 does not equal 14, this statement is also false.
-
So far, we've found three false statements. Let's check the last one:
- 6 + 8 is 14, which is true.
In conclusion, the statement "11 = 1111" is the first and the most straightforward one that is definitely NOT true.
