RE: Order of operations - what is 6÷2(1+2) ?
I find it interesting that TI changed their approach to the priority of implied multiplication over time. (A reference from the above video.)
"Does implied multiplication and explicit multiplication have the same precedence on TI graphing calculators? Implied multiplication has a higher priority than explicit multiplication to allow users to enter expressions, in the same manner as they would be written. For example, the TI-80, TI-81, TI-82, and TI-85 evaluate 1/2X as 1/(2*X), while other products may evaluate the same expression as 1/2*X from left to right. Without this feature, it would be necessary to group 2X in parentheses, something that is typically not done when writing the expression on paper. This order of precedence was changed for the TI-83 family, TI-84 Plus family, TI-89 family, TI-92 Plus, Voyage™ 200 and the TI-Nspire™ Handheld in TI-84 Plus Mode. Implied and explicit multiplication is given the same priority. Please see the graphing calculator guidebooks for additional information." https://education.ti.com/en/customer-sup...sage/11773 Edit: Fixed the above link from TI. |
