B brackets E exponents D division M multiplication A addition S subtraction

2. Multiplying by multiples of ten. (10, 100, 1000, etc.) - move the decimal to the right to make the number larger.

34 x 10 = 340 34 x 100 = 3400 34 x 1000 = 34000

3. Multiplying by multiples of ten & add "0" if needed. (10, 100, 1000, etc.) - move the decimal to the right to make the number larger.

6.71 x 10 = 67.1 6.71 x 100 = 671 6.71 x 1000 = 6710
