$2.$ Perform all multiplications and divisions, working from left to right.

$3.$ Perform all additions and subtractions, working from left to right.

rexample, in the expression $a+b*c,$ first you should multiply $b$ by $c$ and then add $a$ to the total. In other words, the correct expression is $a+b*c=a+(b*c)(a+b)*c.$

Part A

Similar to what you see in your textbook, you can generally omit the multiplication symbol as you answer questions online, except when the symbol is needed to make your meaning clear. For example, $1*{10}^5$ is not the same as ${110}^5.$ When you need to be explicit, type $*($Shift $+8)$ to insert the multiplication operator. You will see a multiplication dot $(*)$ appear in the answer box. Do not use the symbol $x.$ For example, for the expression $ma,$ typing $m*a$ would be correct, but mxa would be incorrect Enter the expression $ma.$

$ma=$
