I'm not saying who, but SOMEONE who was your teacher between grades 1 and 6 told me that you're really bad at math. Like REALLY bad. They recommended you go back to the basics and fill in those gaps with Math Blaster Plus! You know you're really bad at math and need help when they have to emphasize the "Plus!"
So, buy this and successfully get through everything, and you'll be right on track and honestly, you'll probably be far ahead of what current public education teaches kids today with all the new maths.
Does 1x1=2? The quantum universe may say yes, but common sensible Math Blasters Plus! will tell you NO.IYKYK.
Everything is in great condition.
