How to calculate 7 × 9 + 12 △ 3-2 = 75 7 × 9 + 12 △ 3-2 = 23

The fourth, 7 × [(9 + 12) △ 3-2] = 35

Add brackets to the following formula to make the equation hold: (1) 7 × 9 + 12 △ 3-2 = 23 (2) 7 × 9 + 12 △ 3-2 = 75

（7×9+12）÷3-2=23
7×9+12÷（3-2）=75
I hope I can help you

Add brackets to the following formula to make the equation true
9×0.6＋4.8÷0.4－0.3=113.1

9×（0.6＋4.8÷0.4）－0.3=113.1

Add brackets to the formula to make the equation true
① 80-56 * 4 + 4 = 62, ② 80-56 * 4 + 4 = 3, ③ 80-56 * 4 + 4 = 10, ④ 80-56 * 4 + 4 = 73, by the way, I can't type division sign, so I use * instead

Note that * should mean multiply
①80-(56÷4+4)=62
②(80-56)÷(4+4)=3
③(80-56)÷4+4=10
④80-56÷(4+4)=73

There are nine eights in 72, and the formula is 72 divided by 8 equals 9

How do 3 and 4 minus 6 and 10 make up 24
Each number can only be used once. Addition, subtraction, multiplication and division are OK

4-10×(-6)÷3=4+20=24

4 5 6 8 make up 24 with these numbers, but it can't be repeated,

8×（4+5-6）=24
