how to say '6.5×(4.8-1.2×4)' in english?

Answers · 4

Math was my major in college and Fansico's answer is the most precise and correct, except for one thing:
six pint five times open parenthesis four point eight minus THE PRODUCT OF one point two times four close parenthesis
At least that is how I would tell it to another math student.
If I didn't know much math, but wanted to give a clear description, I might say this:
Multipy 1 point 2 times 4
Subtract the result from 4 point 8
Multiply that result times 6 point 5
Following either of these sets of directions should give you the desired result.

six point five times open parenthesis four point eight minus one point two times four right close parenthesis

There is more than one way to say this. Here are a couple of possibilities.
6.5×(4.8-1.2×4)
Six point five multiplied by the quantity, four point eight minus one point two times four.
Six point five times the difference between four point eight and one point two times four.

I'm not sure how to describe the parentheses in maths equations - I'm not a "mathlete" - so here's my attempt anyway:
Six point five times open-bracket four point eight minus one point two times four close-bracket.
...equals?? :)
