Solving an Integer Equation Step by Step
Claro, resolveremos la ecuación paso a paso. La ecuación es la siguiente: \[ 6 + ( -2) - (-3)(-5) \] Primero, sumamos los números enteros. La suma de 6 y -2 es 4. \[ 6 + (-2) = 4 \] Ahora, multiplicamos -3 por -5. Cuando multiplicamos dos números negativos, el resultado es positivo. Por lo tanto, -3 por -5 es 15. \[ (-3) \cdot (-5) = 15 \] Ahora, restamos 15 de 4. La resta de 4 y 15 es -11. \[ 4 - 15 = -11 \] Entonces, el resultado de la ecuación es -11.
Solving an Arithmetic Expression
To solve the given expression: 21 + (-21) + (-4) First, add the positive and negative 21 together. This will cancel each other out because adding a number to its negative is equal to zero: 21 + (-21) = 0 Now you're left with: 0 + (-4) When you add zero to any number, the number remains unchanged. So the answer is simply: 0 + (-4) = -4 The result of the expression is -4.
