How do you use 4 5's to make 100?

Answer 1

You can use four 5's to make 100 by employing arithmetic operations. One way to achieve this is by calculating ( (5 \times 5 \times 5) - 5 ). This simplifies to ( 125 - 5 = 120 ). However, another correct formulation is ( 5 \times (5 + 5 + 5) = 5 \times 15 = 75 ). After checking, you can also use ( (5 \times 5) + (5 \times 5) = 25 + 25 = 50), and finally, ( 5^{2} + 5^{2} + 5 = 100).
