Im a bit rusty but i believe the characters are 数学(translates to "Mathematics") and is pronounced "shuxue"
I think its D but im not sure
Product of the sum of 1/2 and -3/4 and difference of -5/6 and 13/8
= (1/2-3/4)×(-5/6+13/8)
= -1/4×19/24
= -19/96
I would say 8.0 Because if you do 12.6-4.9 you get 7.7 ...hope that helped
