Mathematician trying to educate the 🌎 and make it better

I'm sorry for what happened, @michaelb4jordan and @authenticdelroy. I'm sorry no one apologized. I'm sorry that the harm done to you is being brushed to the side. I'm sorry the BBC aired it unedited. I don't know if it matters, but you deserve an apology, so I'm sorry.

I commit to be inclusive and challenge my own bosses because #BlackGirlsDoMathToo

@ChanaMessinger @j_lanier Now I'm still having trouble finding the square at (1, 3)

[Lisa Dollar @LMoneyMath]

@ChanaMessinger @j_lanier I had the same question, and I also would not have considered turning!

Rochelle's heart was made from a sine function, and it was animated. Very cool!

My students never cease to amaze me whenever I assign this project (#DesmosNames). I get some of their best work and I hear things like "this was fun" and "I felt so smart doing this." These were created using just math equations in Desmos' graphing calculator! #mathISfun #MTBoS

[Lisa Dollar @LMoneyMath]

Love, love, love the Desmos Name Project every time I assign it. Today a student told me that whenever she makes an equation go where she wants it, and then changes the domain to cut it off exactly right, she "feels really smart." #mathISfun

@audiblesupport That really sucks. It's not on my junk mail. Why don't I get stats? Wtf?

[Lisa Dollar @LMoneyMath]

Hey @audible_com I still don't have my stats email!

[Lisa Dollar @LMoneyMath]

Still waiting

[Lisa Dollar @LMoneyMath]

Hey @audible_com where are my #AudibleStats?

@ACTStudent On the right a right triangle with sides 3 and 4 and hypotenuse 6. Impossible.

[Lisa Dollar @LMoneyMath]

Let's play "What's wrong with this ACT problem?"
#MTBoS, #Geometry, #MathEducation #ACT
@ACT

[Lisa Dollar @LMoneyMath]

@ACTStudent The triangles are right triangles. Since the triangle on the left has a height of 4 and a hypotenuse of 5, it's a 3-4-5 triangle. Making that first part of segment DC 3 units long. That means the last part of DC must also be 3 units long. But that would make that triangle...

@jmattmiller @drmcclard Also, x usually represents a kiss, so xxx sounds like...something that might get you a stern warning at least.
