Answer:
✏PROBLEM:
[tex]45 \: – \: 15 \: – \: (2 + 1)² × 4 ÷ 2 =[/tex]
✏ANSWER:
[tex]12[/tex]
✏SOLUTION:
[tex]45 \: – \: 15 \: – \: (2 + 1)² × 4 ÷ 2 [/tex]
Plus 2 and 1
[tex]2 + 1 = 3[/tex]
[tex]45 \: – \: 15 \: – \: 3² × 4 ÷ 2 [/tex]
Calcute the power of 3²
[tex]45 \: – \: 15 \: – \: 9× 4 ÷ 2 [/tex]
Multiply 9 and 4
[tex]9 \times 4 = 36[/tex]
[tex]45 \: – \: 15 \: – \: 36÷ 2 =
[/tex]
Divide 36 and 2
[tex]36 \div 2 = 18[/tex]
[tex]45 – \: 15 \: – \: 18 [/tex]
Minus the 45 and 15
[tex]45 \: - \: 15 = 30[/tex]
[tex]30 - 18[/tex]
Minus them
[tex]30 - 18 = 12[/tex]
So the answer is 12
