If an arithmetical or algebraical term contains ÷ and × , there is at present no agreement as to which sign shall be used first. "It is best to avoid such expressions." For instance, if in 24÷4×2 the signs are used as they occur in the order from left to right, the answer is 12; if the sign × is used first, the answer is 3
.
Some authors follow the rule that the multiplications and divisions shall be taken in the order in which they occur. Other textbook writers direct that multiplications in any order be performed first, then divisions as they occur from left to right. The term a÷b×b
is interpreted by Fisher and Schwatt as (a÷b)×b. An English committee recommends the use of brackets to avoid ambiguity in such cases."
