They equal a minus and two +'s or two -'s equal a + :)
This website tends to omit some crucial operational signs. It will be impossible to answer your question accurately without all the proper signs. Please re-submit it with the equation written out. (plus, minus, equals, etc.)
simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >
It is an equation with the plus or minus signs missing which makes it impossible to solve.
9+8+7+65+4+3+2+1 = 99. So 7 addition signs need to go in 987654321 to get a total of 99.
98 - 76 + 54 + 3 + 21 = 100 :D
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus

yes. equations have an equals signs and expressions don't
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
9+8+7+65+4+3+2+1 = 99. So 7 addition signs need to go in 987654321 to get a total of 99.
When you have two different signs together (a plus and a minus) the minus takes precedence (the minus "wins"). So, for example, 9 + -3 = 9 - 3 = 6.
Without any plus or minus signs or an equality sign the given terms can't be considered to be an equation.
