-7/9 - 5/10 = -7/9 - 1/2 = -14/18 - 9/18 = -23/18
-5/10 + 8/10 = 3/10
-7/10-2/5= =7/10-4/10 =-11/10 =-1.1
Zero.
-15-(-10)= -15+10= -5
-5 - 10 = -15
-3 3/5 minus 9/10 is -4 1/2 or -4.5
- (3/4) - (-5/6) = - (9/12) - (-10/12) = - 9/12 + 10/12 = 1/12
-5 -5 = -10
(-5)-(-3)-(-1)-1-3-5 (-2)-(-1)-1-3-5(-1)-1-3-5 (-2)-3-5 (-5)-5 (-10)
I think you mean "What does negative 10 minus 5 equal?" If not, please correct me. But, the correct answer would be -15 or negative 15.
a negative + negative = negative (ex. -10+-10=-20) a positive + negative = a positive or a negative depending on how high the negative number is (ex1. 10+-5=5 , ex2. 10+-15=-5) a positive + positive = a positive "obviously" (ex. 2+2=4) a negative - negative = positive (ex. -5--10=5) because the minus sign and the negative sign automatically turn into an addition sign.
A negative number minus a positive number equals a minus number( E.G -5 - [+]5 = -10)A negative number minus a negative number equals a positive number ( If the number's big enough)(E.G -5 - -5 = 0 )Hope this helps :)
