Wolfram Blog: From Plant Roots to Deep Space Wolfram Community Computational Explorations
posted on July 29, 2021 by Mads Bahrami

For the past few months, Wolfram Community members have shared their computational explorations on topics ranging from computational art and games to original, published research. I’ll comment here on just a few of their many interesting examples. Please feel free to share your ideas with us at Wolfram Community, and let’s explore the world computationally. […]

Folks, how to expand $(1+2)^3$ without evaluating the final result? I want to treat 1 and 2 as if they are variables.
Invoking Expand[(1 + x)^3] /. x -> 2 produces 27 rather than 1+3 2+3 2^2+2^3.
Using spaces for multiplication is fine.
Please kindly ping me if you can solve my problem above. Thank you.

@WhoSaveMeSaveEntireWorld Some ways that come to mind: 
Expand[(HoldForm[1] + HoldForm[2])^3]
Expand[(x + y)^3] /. {x -> HoldForm[1], y -> HoldForm[2]}
Expand[("1" + "2")^3]

@MichaelE2: You are genius. Thank you very much. I choose the second way.
