1. Use the standard order of operations.
3*2*4 = (3*2)*4 = 6*4 = 24
2. Double 3, then multiply the result by 4.
3+3 = 6
6*4 = 24
3. Use the commutative property to rearrange the ordering
(3*4)*2 = 12*2 = 24 or
(2*4)*3 = 8*3 = 24
4. Recognize 2*4 = 8 = 10 - 2.
3*8 = 3*(10-2) = 30 - 6 = 24
5. Get a bunch of cubes. Arrange them into a pile 3 cubes wide, 4 cubes long, and 2 cubes deep. Count how many cubes that is.
3*2*4 = (3*2)*4 = 6*4 = 24
