Life While We're Young的歌詞如下：
Verse 1:
We were young and full of dreams
With no care in the world
Looking up at the sky
With no worries at all
Chorus:
Life while we're young
Is a beautiful thing
Take each day as it comes
Don't let it slip away

Through the highs and lows of life
We've learned to stand up tall
Through the tears and laughter too
We've grown into ourselves
Chorus:
Life while we're young
Is a beautiful thing
Take each day as it comes
Don't let it slip away

When we look back on these years
We'll smile and say we did
All the things we dreamed of
And more than we dared to do

Life while we're young
Is a beautiful thing
Take each day as it comes
Don't let it slip away

數學符號中的等價於是一個數學術語，用於表示兩個數學對象之間的一種關係。具體來說，如果兩個數學對象之間的某種關係與另一個數學對象等價，那么這兩個數學對象就稱為等價的。例如，當兩個向量在相同的方向上具有相同的長度時，它們就等價於同一個向量。此外，等價符號通常使用“=”來表示。在數學中，等價關係可以用於對數學對象進行分類，並確定哪些對象是相同的。同時，等價符號還可以用於證明數學定理和解決數學問題。
