Alright, let's solve this math problem step by step. First, we have the number 40. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 65. So, we're going to take the number 40 and add it to itself 65 times.
Step 1: 0 + 40 = 40
Step 2: 40 + 40 = 80
Step 3: 80 + 40 = 120
Step 4: 120 + 40 = 160
Step 5: 160 + 40 = 200
Step 6: 200 + 40 = 240
Step 7: 240 + 40 = 280
Step 8: 280 + 40 = 320
Step 9: 320 + 40 = 360
Step 10: 360 + 40 = 400
Step 11: 400 + 40 = 440
Step 12: 440 + 40 = 480
Step 13: 480 + 40 = 520
Step 14: 520 + 40 = 560
Step 15: 560 + 40 = 600
Step 16: 600 + 40 = 640
Step 17: 640 + 40 = 680
Step 18: 680 + 40 = 720
Step 19: 720 + 40 = 760
Step 20: 760 + 40 = 800
Step 21: 800 + 40 = 840
Step 22: 840 + 40 = 880
Step 23: 880 + 40 = 920
Step 24: 920 + 40 = 960
Step 25: 960 + 40 = 1000
Step 26: 1000 + 40 = 1040
Step 27: 1040 + 40 = 1080
Step 28: 1080 + 40 = 1120
Step 29: 1120 + 40 = 1160
Step 30: 1160 + 40 = 1200
Step 31: 1200 + 40 = 1240
Step 32: 1240 + 40 = 1280
Step 33: 1280 + 40 = 1320
Step 34: 1320 + 40 = 1360
Step 35: 1360 + 40 = 1400
Step 36: 1400 + 40 = 1440
Step 37: 1440 + 40 = 1480
Step 38: 1480 + 40 = 1520
Step 39: 1520 + 40 = 1560
Step 40: 1560 + 40 = 1600
Step 41: 1600 + 40 = 1640
Step 42: 1640 + 40 = 1680
Step 43: 1680 + 40 = 1720
Step 44: 1720 + 40 = 1760
Step 45: 1760 + 40 = 1800
Step 46: 1800 + 40 = 1840
Step 47: 1840 + 40 = 1880
Step 48: 1880 + 40 = 1920
Step 49: 1920 + 40 = 1960
Step 50: 1960 + 40 = 2000
Step 51: 2000 + 40 = 2040
Step 52: 2040 + 40 = 2080
Step 53: 2080 + 40 = 2120
Step 54: 2120 + 40 = 2160
Step 55: 2160 + 40 = 2200
Step 56: 2200 + 40 = 2240
Step 57: 2240 + 40 = 2280
Step 58: 2280 + 40 = 2320
Step 59: 2320 + 40 = 2360
Step 60: 2360 + 40 = 2400
Step 61: 2400 + 40 = 2440
Step 62: 2440 + 40 = 2480
Step 63: 2480 + 40 = 2520
Step 64: 2520 + 40 = 2560
Step 65: 2560 + 40 = 2600

So, 40*65 = 2600
