-7 + -3 =

To calculate -7 + (-3), we follow the order of operations: * Parentheses: There are no parentheses in this expression, so we move on to the next step. * Exponents: There are no exponents in this expression, so we move on to the next step. * Multiplication and Division (from left to right): There are no multiplication or division operations in this expression, so we move on to the next step. * Addition and Subtraction (from left to right): We have two addition operations: -7 + (-3). * For the first addition, we combine the negative signs: -7 - 3. * Since both numbers are negative, the sum is also negative: -7 - 3 = -10. Therefore, the answer to the expression -7 + (-3) is -10. In simpler terms, we are adding two negative numbers. When adding negative numbers, we combine their values and keep the negative sign. In this case, -7 and -3 both contribute negative values, resulting in a total negative value of -10.
