[Verse 1]
Your body's an isosceles (Alright)
And I'm just tryna try angles (Okay)
Your love is trigonometry (Yeah)
Just tryna solve the whole equation

[Pre-Chorus]
What's it about, what you about? I wanna love you
Figure you out, figure you out, so I can touch you
Should we do that? Can I do that, baby?
Answers are usually in the back (Hey)

[Chorus]
Substitution, add me in
Multiply my love, is that too much? (Can I do that?)
Substitution, what's the problem, girl?
Add me in (Yeah), woo

[Post-Chorus]
Just add me⁠⁠—
Baby, just add me in
Would you add me⁠—
Add me in

[Verse 2]
I'll calculate a home invasion (Yeah, add it up)
Divide your legs and count to three (Three, two, one, come on)
He's just not the answer, baby
And that's just my hypothesis

[Pre-Chorus]
What's it about, what you about? I wanna love you
Figure you out, figure you out, so I can touch you
Should we do that? Can I do that, baby?
Answers are usually in the back

[Chorus]
Substitution, add me in
Multiply my love, is that too much? (Can I do that?)
Substitution, what's the problem, girl?
Add me in (Yeah), woo

[Bridge]
What if I said I loved you?
I need you, would you care? (Ooh)
So many things that I could learn
And baby, if we do the math
It would equal out to me inside of you

[Chorus]
Substitution, add me in (Woah, yeah)
Multiply my love, is that too much? (Can I do that?)
Substitution, what's the problem, girl?
Add me in (Yeah), woo
Substitution, add me in
Multiply my love, is that too much? (Can I do that?)
Substitution, what's the problem, girl?
Add me in (Yeah), woo

[Post-Chorus]
Just add me⁠⁠—
Baby, just add me in (Ooh)
Would you add me⁠—
Add me in
Just add me⁠⁠—
Baby, just add me in (Ooh)
Would you add me⁠—
Add me in
