        4.<\/strong> 8+8+___=2\u00d7108 + 8 + \\_\\_\\_ = 2 \\times 10<\/h3>\n\n\n\n
          \n
        • Left part: 8+8=168 + 8 = 16<\/li>\n\n\n\n
        • Right side: 2\u00d710=202 \\times 10 = 20<\/li>\n\n\n\n
        • 16+___=20\u21d220\u221216=416 + \\_\\_\\_ = 20 \\Rightarrow 20 – 16 = 4

          5.<\/strong> 40\u2212(6+5)=11+1040 – (6 + 5) = 11 + 10<\/h3>\n\n\n\n
            \n
          • Inside parentheses: 6+5=116 + 5 = 11<\/li>\n\n\n\n
          • Left side: 40\u221211=2940 – 11 = 29<\/li>\n\n\n\n
          • Right side: 11+10=2111 + 10 = 21<\/li>\n\n\n\n
          • 29\u22602129 \\ne 21, so check if the equation is already<\/strong> correct or if there’s a missing number.<\/li>\n<\/ul>\n\n\n\n

            Let\u2019s suppose the original expression is:
            40\u2212(6+5)=11+___40 – (6 + 5) = 11 + \\_\\_\\_<\/p>\n\n\n\n

              \n
            • Left side: 40\u221211=2940 – 11 = 29<\/li>\n\n\n\n
            • 29=11+___\u21d229\u221211=1829 = 11 + \\_\\_\\_ \\Rightarrow 29 – 11 = 18

                Explanation<\/strong><\/h2>\n\n\n\n

                These problems test your understanding of basic arithmetic operations\u2014addition, subtraction, multiplication, and order of operations\u2014and how to manipulate equations to find missing values.<\/p>\n\n\n\n

                In the first problem, we begin with multiplication: 8\u00d78=648 \\times 8 = 64. The other side of the equation is a sum that partially adds to 44. To make both sides equal, we determine what number must be added to 44 to get 64, which is 20.<\/p>\n\n\n\n

                The second problem uses subtraction. You are given a difference (50 minus a number) that equals a known sum (28). To find the missing number, subtract 28 from 50, giving 22.<\/p>\n\n\n\n

                In the third equation, a number plus 12 equals another known sum (24). To isolate the missing number, you subtract 12 from 24, which results in 12.<\/p>\n\n\n\n

                The fourth question tests your knowledge of both addition and multiplication. The total needs to equal 20. Since 8 + 8 = 16, we determine the missing number by subtracting 16 from 20, which gives 4.<\/p>\n\n\n\n

                Finally, the fifth problem involves both subtraction and parentheses. First, compute the value inside the parentheses (6 + 5 = 11), then subtract from 40 to get 29. The right side of the equation is 11 + a missing number. Solving 11+x=2911 + x = 29, we find x = 18.<\/p>\n\n\n\n

                Understanding how to isolate variables and balance both sides of an equation is essential for solving math problems like these efficiently and accurately.<\/p>\n\n\n\n
