Line 7:
Line 7: − ==Symbol==+ − Several conventions are used to indicate multiplication. − *For simple numbers, the symbol (<big><math>\times</math></big>) used looks much like the letter "X", as in the examples above. − *Since the "X" looks like a letter, and letters are commonly used in algebra to indicate [[unknown]]s, or [[variable]]s, the "dot" is frequently used: A • B = B • A. − *Alternatively a period may be used to denote multiplication − *Also, in [[algebra]]ic use, quantities are simply juxtaposed to indicate that they are to be multiplied: − : Y = 3aX + 4bZ
→Symbol: section needs rewriting - it causes more confusion than it explains anything
:For example <big><math>3\times 2 </math></big> (spoken as "three times two") is the sum of 3 + 3 = 6.
