Select the expression that matches the following phrase:
The sum of B
and the product of A
and x
.
expr(["+", ["*", A, "x"], B])
expr(["+", ["*", -A, "x"], B])
expr(["+", ["*", A, "x"], -B])
expr(["+", ["*", B, "x"], A])
expr(["+", ["*", -B, "x"], -A])
What is the product of A
and x
?
What is the sum of B
and expr(["*", A, "x"])
?
Take the quantity A
times x
, and then add B
.
What is the quantity of A
times x
?
What does adding B
do?
B
plus the product of A
and x
.
What is the product of A
and x
?
What is B
plus expr(["*", A, "x"])
?
The sum of B
and the quantity A
times x
.
What is the quantity A
times x
?
What is the sum of B
and expr(["*", A, "x"])
?
Let's break this problem into smaller and easier pieces.
A \times x = \color{orange}{expr(["*", A, "x"])}
Ax
{} + B
So, the original phrase can be written as expr(["+", ["*", A, "x"], B])
.
