Introduce slope, slope, and more slope, with this comprehensive video about....slope! Start with the slope formula and transition to counting the slope from a line on a coordinate plane. Your mathematicians will be able to see the...

Many young mathematicians get slightly confused when they are introduced to the concept of exponents. This resource will ensure that they never get confused again. Sal explains, quite emphatically, that six to the eighth power is NOT the...

Your young mathematicians can solve this problem along with Sal. They will add 4/9 and 11/12 by finding a number that evenly divides both 9 and 12. Sal fully explains the process of finding a common denominator in an evident and...
