6 ? 6 ? 6 ? 6
Insert the symbols +, -, *, and / between the 6's to make each equation below valid. The only catch is that the equations must read from left to right, ignoring normal arithmetic order. For example, 3 + 3 * 3 would equal 18, not 12 (3+3=6; 6*3=18).
1. 42 = 6 ? 6 ? 6 ? 6
2. 48 = 6 ? 6 ? 6 ? 6
3. 66 = 6 ? 6 ? 6 ? 6
4. 108 = 6 ? 6 ? 6 ? 6
5. 180 = 6 ? 6 ? 6 ? 6
1. 42 = 6 ? 6 ? 6 ? 6
2. 48 = 6 ? 6 ? 6 ? 6
3. 66 = 6 ? 6 ? 6 ? 6
4. 108 = 6 ? 6 ? 6 ? 6
5. 180 = 6 ? 6 ? 6 ? 6
Answer
1. 42 = 6 / 6 + 6 * 62. 48 = 6 * 6 + 6 + 6
3. 66 = 6 + 6 * 6 - 6
4. 108 = 6 + 6 + 6 * 6
5. 180 = 6 * 6 - 6 * 6
