a) \( (+5)+(+10)= \) b) \( (-5)+(-10)= \) c) \( (+7)+(-2)= \) d) \( (-4)+(+4)= \) e) \( (-7)+(+11)= \) f) \( (-8)+(+6)= \) g) \( (-4)-(-3)= \) h) \( (-8)-(+2)= \) i) \( (11)-(-3)= \) j) \( (-5)-(-2)-(7)= \)

Let's break these calculations down! a) \( (+5) + (+10) = +15 \) b) \( (-5) + (-10) = -15 \) c) \( (+7) + (-2) = +5 \) d) \( (-4) + (+4) = 0 \) e) \( (-7) + (+11) = +4 \) f) \( (-8) + (+6) = -2 \) g) \( (-4) - (-3) = -4 + 3 = -1 \) h) \( (-8) - (+2) = -8 - 2 = -10 \) i) \( (11) - (-3) = 11 + 3 = +14 \) j) \( (-5) - (-2) - (7) = -5 + 2 - 7 = -10 \) Now, let’s dive a bit deeper! Adding positive numbers is like throwing confetti at a party—you just keep getting more joy! When combining negative numbers, it’s like accumulating rain clouds—together they add up to a stormier day. For subtracting negatives, remember they flip signs like magic! Subtracting a negative is the same as adding a positive, just picture them as friendly numbers giving high-fives!
