Hello, meho6!

Is that really a "54" in the list?

Using the following numbers in exact order and the total has to equal 100: 3, 5, 6, 2, 54, 5
3 \times \bigg[5 + (6\times2)\bigg] + 54 - 5 \;=\;100

If those are separate digits: .3, 5, 6, 2, 5, 4, 5

. . \bigg[(3+5) \div (6+2)\bigg] \times 5 \times 4 \times 5 \;=\;100
