# Thread: help with writing math expressions

1. ## help with writing math expressions

i need help with writing expressions
A) double the sum of 25 and 8
i think it is(2x25+8)
B) the quotient of 15 and 3 subtracted from the product of 4 and 9
i think it is (5/3-4x9)
C) the difference between 20 and 5 multiplied by the sum of 8 and 2
I think it is 20-5x8+2
D) 3 times the square root of the sum of
9 and 7 i think it is (3x9(2)+7(2)
(2) = squared as i don't know how to write that on a computer.

any help would be greatful or just letting me know i'm on the right track i just can't seem to get it

C) the difference between 20 and 5 multiplied by the sum of 8 and 2
I think it is (20-5)x(8+2)

D) 3 times the square root of the sum of
9 and 7 i think it is 3x sqrt(9 +7) Mr F says: It's square root, not squared.

(2) = squared as i don't know how to write that on a computer.
