It depends on what the sign is before your number. A positive sign in front of the number indicates that the inside of the cell is more positive when compared to the outside; a negative sign in front of the number indicates that the cell is more negative compared to the outside.
The resting potential of a neuron is always negative when compared to the outside of the neuron, and usually lies around -90mV. For different cells in the body, the resting potential may vary but it will always be negative :)!

Why is the resting potential value of a membrane negative?
The resting membrane potential is the difference between the inside of the cell relative to the outside. The outside is always taken as 0mv. The resting membrane potential is negative because there is a higher concentration of potassium ions outside the cell (because the membrane is more permeable to potassium ions) than inside. Since potassium ions are positively charged this leads to a negative value.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
When a neuron's resting potential is occurring the neuron is what charge on the inside?
resting potiental
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
Are there more sodium ions inside or outside a cardiac muscle cell during the resting membrane potential?
Outside
What ion determines the resting membrane potential of nerve and muscle?
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
A resting potential is caused by a difference in the concentration of certain ions inside and outside the cell?
True
What is the state when an electrical charge of a neuron is said to be at a resting potential?
The resting potential is the normal equilibrium charge difference (potential gradient) across the neuronal membrane, created by the imbalance in sodium, potassium, and chloride ions inside and outside the neuron.
When a neuron is in a resting state the majority of the particles in the fluid surrounding the neuron are?
polarized
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental
